Is the ABUS 2ALHB/40-75 the right lockout/tagout padlock for deep hasps and single-worker multi-point isolation?

Short answer: If one authorized worker needs to lock several isolation points at once — or reach through deep, stacked, or scissor-style lockout hasps a standard shackle can't span — the ABUS 2ALHB/40-75 is a strong, purpose-built choice. Its long shackle and keyed-alike set let that worker carry one key for many locks. But if you're issuing personal locks to a crew, you want keyed-different instead; see how to choose a lockout padlock before you order, and browse the full range of lockout padlocks.

ABUS 2ALHB/40-75 Lockout Padlock Review (2026)

In a compliant program built around what is lockout/tagout, the padlock is the device that physically holds an energy-isolating point — a breaker, valve, or disconnect — in the safe position so equipment cannot be re-energized while a worker is exposed. The ABUS 2ALHB/40-75 fills a specific niche in that program: it is a long-shackle, 40mm aluminum lockout padlock supplied keyed alike, where every lock in the matched set opens with one key. That keying is what separates it from the per-worker norm. OSHA 29 CFR 1910.147 is built on one-worker-one-lock-one-key personal energy control, which most programs satisfy with keyed-different locks like the ABUS 74/40 10-pack or the Brady SafeKey keyed-different. The 2ALHB/40-75 instead serves the single worker who must hold several isolation points simultaneously, or who needs the extended shackle to span deep lockout hasps that a standard shackle can't reach. Read how to perform LOTO to see where it fits in the sequence, and the full lockout/tagout devices catalog for the rest of the kit.

Editorial verdict — 4.3/5
For a single worker isolating multiple or hard-to-reach points, the ABUS 2ALHB/40-75 earns its keep with build quality and the long shackle's reach; just confirm keyed-alike — not keyed-different — is what your procedure calls for before you buy.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for

• Maintenance technicians who routinely lock several isolation points at once and want one key for the set — pair with a personal LOTO kit
• Electricians and mechanics working deep panels or stacked lockout hasps where a standard shackle won't reach
• Facilities and plant teams standardizing a single-worker multi-point procedure documented in how to perform LOTO
• Safety managers who already issue keyed-different personal locks like the ABUS 74/40 set and need a long-shackle specialty lock on top
• Contractors servicing oversized disconnects and valves who need the extra shackle clearance from the lockout padlocks range

What the ABUS 2ALHB/40-75 does well

Long shackle solves real reach problems

The "75" extended shackle is the headline feature: it spans deep hasps, scissor clamps, and stacked lockout hasps that defeat a standard-shackle lock. If your isolation points have been awkward to lock, this is the format that fixes it — see how to choose a lockout padlock.

Aluminum body carries well all shift

The 40mm aluminum body keeps the lock light on a tool belt across a long day and resists corrosion in field conditions — the same practical logic behind aluminum siblings like the Brady SafeKey blue in our lockout padlocks lineup.

Keyed-alike streamlines single-worker multi-point lockout

When one authorized employee must hold several isolation points at once, carrying ten unique keys is a nuisance; a keyed-alike set means one key opens the whole group. That is the legitimate use case the 2ALHB/40-75 is built for, distinct from the crew-issuance model in what is lockout/tagout.

Purpose-built, not a repurposed security lock

This is a dedicated lockout/tagout device, standardized and identifiable as a safety padlock — durable, substantial, and single-purpose as 1910.147 expects, in the same class as the American Lock A1107R.

Where the ABUS 2ALHB/40-75 falls short

Keyed-alike is not personal-protection keying

The core of 1910.147 is each worker controlling the only key to their own lock. A keyed-alike set breaks that if used for crew issuance — anyone with the shared key can remove any lock. For per-worker personal control, choose keyed-different like the ABUS 74/40 10-pack and read lockout vs tagout.

The long shackle is more exposed

The extra reach that makes deep hasps possible also leaves more shackle exposed and gives bolt cutters a bigger target. Where the geometry allows it, a standard-shackle lock from the lockout padlocks range is the tidier, lower-profile choice.

Single-lock economics for crews

Bought one at a time, equipping a team adds up fast versus economy multipacks such as the TRADESAFE TS1KD10R red 10-pack. Reserve the 2ALHB/40-75 for the specialty long-shackle role, not blanket issuance.

No stated dielectric rating

The listing describes an aluminum body but does not claim a non-conductive/dielectric rating. For energized electrical work under 1910.333, specify a lock the manufacturer rates non-conductive — like the thermoplastic ABUS 74/40 — rather than assuming.

When to step up from the ABUS 2ALHB/40-75

Step up from a standard-shackle lock to the 2ALHB/40-75 only when reach is the problem — deep hasps, scissor clamps, or stacked lockout hasps that a normal shackle can't close around. If your real need is per-worker issuance rather than reach, step sideways to a keyed-different option: the ABUS 74/40 10-pack or Brady SafeKey KD for individuals, or the TRADESAFE TS1KD10R and TRADESAFE TSKAU10YL packs for crews. And when the geometry isn't a hasp at all — a valve wheel or bulky handle — a cable lockout like the QWORK QS8899 is the right step, not a longer shackle.

Category context

Three choices define a padlock's fit in your program. First, device type: a padlock holds a hasp or single isolation point; a lockout hasp lets multiple workers each apply their own lock to one point for group lockout; a personal LOTO kit stages padlocks, hasps, and tags together; and a lockout station stages devices for a whole area. Second, keying: keyed-different (KD) gives every lock a unique key and is the default for per-worker personal control, while keyed-alike (KA) — what the 2ALHB/40-75 ships as — puts one key across a matched set, which only makes sense for a single worker holding many points or a controlled supervisor set. Third, personal vs group: one-worker-one-lock-one-key is the baseline, but group lockout adds hasps and lockout tags so several workers share one isolation point safely. A tag identifies the worker but is never an energy-isolating device on its own — see lockout vs tagout. Map your need against those three before you commit, using how to choose a lockout padlock.

Total cost of ownership

On durability, the aluminum body and ABUS platform are built to survive daily field carry, so replacement is driven more by loss and key control than by wear — the usual story across quality lockout padlocks. The real cost question is format. As a single lock, the 2ALHB/40-75 costs more per unit than economy multipacks, so it pays off only in its specialty long-shackle role; buying it to equip a crew is poor economics next to the TRADESAFE TS1KD10R 10-pack or the ABUS 74/40 set. Factor in key management too: a keyed-alike set concentrates risk in one key, so losing it means re-keying or replacing the whole group rather than a single lock. Budget for spare-key control per your written procedure in how to perform LOTO, and stage replacements through a lockout station so a missing lock never stalls a job.

Final verdict

Buy the ABUS 2ALHB/40-75 for one job and buy it well: a single authorized worker who must lock multiple isolation points on one key, or who needs the long shackle to reach through deep and stacked lockout hasps. For that worker it's a clean, durable specialty lock from the lockout padlocks range. If you're issuing personal locks to a crew, skip it and choose keyed-different — the ABUS 74/40 10-pack, Brady SafeKey KD, or the TRADESAFE TS1KD10R pack. For energized electrical isolation, specify a manufacturer-rated non-conductive lock, and for valve-wheel or irregular geometry reach for a cable lockout instead. Confirm the match against what is lockout/tagout and the full lockout/tagout devices catalog before ordering.

ABUS 2ALHB/40-75 FAQ

Is the ABUS 2ALHB/40-75 OSHA 1910.147 compliant?

It is a durable, identifiable, single-purpose lockout padlock, which is what 1910.147 requires of an energy-isolating device. Compliance, though, depends on how you deploy it: the standard is built on one-worker-one-lock-one-key personal control. Used as a single worker's tool across multiple points it fits; used to issue shared-key locks to a crew it does not. Read what is lockout/tagout for the full requirement.

What does keyed alike mean, and why does it matter here?

Keyed alike means every lock in the matched set opens with the same key. That suits a single authorized worker managing several isolation points without juggling many keys. It is the opposite of keyed-different, where each lock has its own unique key for per-worker personal protection. See how to choose a lockout padlock for which keying your procedure needs.

When should I choose keyed-different instead of this keyed-alike lock?

Choose keyed-different whenever you issue personal locks to individual workers — the heart of 1910.147. With keyed-different, only the worker holding that unique key can remove their lock. For that, look at the ABUS 74/40 10-pack or the Brady SafeKey KD, not a keyed-alike set.

What is the long shackle for?

The extended "75" shackle reaches through deep hasps, scissor clamps, and stacked lockout hasps that a standard shackle cannot span. If you've struggled to close a lock around a thick or layered isolation point, the long shackle is the fix. Where clearance is tight, a standard-shackle lock is lower-profile.

Is the ABUS 2ALHB/40-75 non-conductive for electrical work?

The listing describes a 40mm aluminum body but does not state a dielectric or non-conductive rating, so don't assume one. For energized electrical isolation under 1910.333, specify a lock the manufacturer rates non-conductive — the thermoplastic ABUS 74/40 is one example in our lockout padlocks range.

How does it compare to the ABUS 74/40 10-pack?

The 74/40 ships as a keyed-different 10-pack of non-conductive thermoplastic locks built for per-worker issuance and electrical work; the 2ALHB/40-75 is a single keyed-alike aluminum lock with a long shackle for one worker's multi-point or deep-hasp use. They solve different problems — compare both via how to choose a lockout padlock.

Can I use one ABUS 2ALHB/40-75 set for my whole maintenance crew?

Not for personal-protection issuance. A keyed-alike set means anyone with the shared key can remove any lock, which breaks the one-worker-one-lock-one-key rule. To equip a crew, use keyed-different multipacks like the TRADESAFE TS1KD10R or TRADESAFE TSKAU10YL.

Is a longer shackle less secure?

It is more exposed. The extra reach that lets it span deep hasps also leaves more shackle out and gives bolt cutters a larger target. That tradeoff is acceptable when you genuinely need the reach; when you don't, a standard-shackle lock from the lockout padlocks range is tidier and harder to attack.

Padlock, hasp, or cable lock — which do I need?

A padlock locks a single point or hasp; a lockout hasp lets multiple workers each lock one shared point for group lockout; and a cable lockout like the QWORK QS8899 wraps valve wheels and irregular geometry a rigid shackle can't. The 2ALHB/40-75 is a padlock, so it needs a hasp or a lockable point.

Does a lockout tag replace this padlock?

No. A lockout tag identifies who applied the lock and warns others, but a tag alone is not an energy-isolating device. The padlock is what physically prevents re-energization. See lockout vs tagout for why tagout-only is the weaker option.

How many of these should I buy?

Buy the number of isolation points a single worker needs to hold at once — that's the keyed-alike set's purpose. Don't buy it to size a whole crew; for that, count workers and order keyed-different multipacks like the ABUS 74/40 10-pack. Plan it against how to perform LOTO.

Where does this fit in the lockout sequence?

After you notify affected employees, shut down, and isolate the energy source, the padlock goes on the energy-isolating device to hold it safe, then you apply your tag. The 2ALHB/40-75 handles that lock step where reach or multi-point keying is the constraint. The full sequence is in how to perform LOTO.

Is aluminum durable enough for daily field use?

Yes — aluminum keeps the lock light for tool-belt carry and resists corrosion, which is why it's a common LOTO body material across the lockout padlocks range, including the Brady SafeKey aluminum locks. It is standard-duty, not a hardened high-security padlock, which is appropriate for safety lockout.

How should I manage the shared key on a keyed-alike set?

Treat the single key as a control point: keep spare keys in a controlled location per your written program, and limit who holds the working key. Because one key opens the whole set, losing it can mean re-keying or replacing the group — a real consideration covered in how to choose a lockout padlock.

Should I keep this lock in a personal kit or a station?

Either, depending on your program. A personal LOTO kit keeps one worker's devices ready to carry to the machine, while a lockout station stages shared devices for an area. A specialty long-shackle lock often lives in the kit of the worker who needs it.

What's the difference between this and the American Lock A1107R?

The A1107R is a red, standard-shackle single-purpose safety padlock for color-coded crew assignment; the 2ALHB/40-75 is an aluminum long-shackle keyed-alike lock for reach and single-worker multi-point use. Pick by your constraint — color-coding and per-worker issuance versus deep-hasp reach. Both sit in the lockout/tagout devices catalog.

Is the ABUS 2ALHB/40-75 good value?

For its specialty role, yes — a durable long-shackle keyed-alike lock that solves reach and multi-point keying cleanly. As a single lock it is poor value for outfitting a crew, where economy keyed-different packs like the TRADESAFE TS1KD10R win on cost per worker. Buy it for the job it's built for.
