American Lock A1107R Safety Lockout Padlock — Red (OSHA Lockout/Tagout) Overview
The American Lock A1107R Safety Lockout Padlock is a red, single-purpose padlock built for OSHA 29 CFR 1910.147 energy-control procedures. In lockout/tagout, an energy-isolating device — a breaker, valve, or disconnect — is moved to the safe position and then physically locked so the equipment cannot be re-energized while someone is servicing it. The A1107R is the lock that holds that isolation in place.
This is a safety lockout padlock, not a general-security lock. The format is standardized for LOTO: a distinct red body for color-coded crew assignment, a keyed cylinder that stays with the worker, and a profile sized to fit the hole patterns on breaker lockouts, valve covers, and lockout hasps. It belongs in the same kit as your lockout tagout tags, cable lockouts, and plug lockouts.
The core rule is one lock, one worker, one key. Each authorized employee applies their own A1107R and attaches a tag identifying who owns it; only that person removes it when their work is complete. On multi-worker jobs, several A1107R locks share a lockout hasp so the equipment stays locked until the last worker clears. Stage spares at a lockout station so a fresh lock and tag are always within reach.
The red A1107R is one color in the American Lock A1107 series, which is offered across a range of body colors for departmental or crew coding. Browse the full range of lockout padlocks and the broader lockout tagout program to standardize your facility. Before ordering a crew quantity, confirm with your supplier whether you need keyed-different locks (each unique — the norm for individual LOTO) or keyed-alike sets (one key opens a group), since that choice is set at purchase.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Individual worker lockout on a breaker or disconnect | Ideal | Each worker applies their own red A1107R plus a name tag; only they remove it. Keyed-different is the standard choice so no one else can open your lock. |
| Multi-worker / group lockout on one isolation point | Ideal with a hasp | Pair the A1107R with a lockout hasp so every worker hangs their own lock; the energy point stays locked until the last lock comes off. |
| Color-coded crew or shift assignment | Strong | Use red A1107R for a specific crew, shift, or department and a different A1107-series color for others to read ownership at a glance. |
| Electrical isolation around live or potentially live circuits | Verify | Many safety padlocks use a non-conductive shackle for electrical work — confirm the A1107R shackle material with your supplier before relying on it near energized parts. |
| General-purpose security (gates, toolboxes, storage) | Not intended | This is a dedicated LOTO safety padlock. Keep it reserved for energy control so locks are never in doubt during a lockout. |
Lockout/tagout devices are part of an OSHA 29 CFR 1910.147 energy-control program. A lock isolates hazardous energy (electrical, hydraulic, pneumatic, mechanical) so equipment cannot be re-energized during service. Each authorized worker applies their own keyed-different lock and a tag; never share or remove another worker's lock. The hardware is only as good as the written procedure, training, and verification of zero energy behind it. Browse lockout/tagout devices.
Pros & Cons
Pros
- Purpose-built red safety lockout padlock for OSHA 1910.147 energy-control procedures
- High-visibility red body supports color-coded crew, shift, or department assignment
- Part of the American Lock A1107 series, offered in multiple colors for a standardized program
- Works with lockout hasps for multi-worker group lockout on a single isolation point
- Keeps the one-lock/one-worker/one-key rule simple and enforceable on the floor
- Pairs cleanly with tags, stations, and cable/plug lockouts for a complete LOTO kit
Cons
- Keyed-alike vs keyed-different must be confirmed at purchase — not changeable after
- Dedicated LOTO lock, not intended for general security use
- Shackle material and non-conductive suitability should be verified before electrical work
- A single padlock does not lock multiple workers onto one point without a separate hasp
How It Compares
The A1107R is the red option in the American Lock A1107 safety-padlock series. Color is the main difference within the series — body color drives crew, shift, or department coding while the lock format stays consistent. To compare against other brands and formats, browse the full lockout padlocks collection.
| Model | Color | Best for |
|---|---|---|
| A1107R (this lock) | Red | Default high-visibility color; common for a primary crew or as the standard floor lock |
| A1107 series — other colors | Blue, yellow, green, etc. | Assigning a different color to each crew, shift, or department for at-a-glance ownership |
| A1107 series — keyed-alike sets | Any series color | One worker or supervisor needing several locks opened by a single key |
Match the lock to the hardware too: add lockout hasps for group lockout, cable lockouts for awkward isolation points, and plug lockouts for cord-connected equipment. Stock the whole program from one lockout station.

Frequently Asked Questions
What is the American Lock A1107R used for?
It is a red safety lockout padlock for OSHA 29 CFR 1910.147 energy control. It locks an energy-isolating device — a breaker, valve, or disconnect — in the safe position so equipment cannot be re-energized while a worker services it. Browse more lockout padlocks.
Is the A1107R keyed alike or keyed different?
Keying is set at purchase, so confirm it with your supplier before ordering a crew quantity. Keyed-different (each lock unique) is the standard choice for individual LOTO; keyed-alike (one key opens a group) suits a single worker carrying several locks. We do not assert this unit's keying beyond what your order specifies.
Why is this lockout padlock red?
The red body gives high visibility and supports color-coded assignment — you can reserve red for a specific crew, shift, or department and use other American Lock A1107-series colors for others, so ownership is readable at a glance across the full lockout tagout program.
Can multiple workers lock out the same equipment with A1107R locks?
Yes — add a lockout hasp. Each worker hangs their own A1107R on the hasp, and the energy-isolating device stays locked until the last worker removes their lock. One padlock alone secures one worker to one point.
Does each worker need their own A1107R lock and tag?
Yes. The core LOTO rule is one lock, one worker, one key, plus a tag identifying the owner. Only the worker who applied the A1107R removes it. Pair locks with lockout tagout tags so every lock is clearly attributed.
Is the A1107R non-conductive for electrical work?
Many safety padlocks use a non-conductive shackle for electrical lockout, but we do not assert the A1107R shackle material beyond what the listing supports. Confirm shackle material and electrical suitability with your supplier before relying on it near energized parts.
What shackle size and body material does the A1107R have?
We do not list a shackle dimension or body material we cannot confirm from the product data. Verify the shackle diameter, clearance, and body material with the manufacturer spec sheet to be sure it fits your lockout hasps and isolation devices.
Will the A1107R fit my breaker lockouts and hasps?
Safety padlocks are sized to pass through standard LOTO hole patterns, but always check the shackle clearance against your specific devices. For tight or unusual points, a cable lockout can reach where a padlock shackle cannot.
Can I use the A1107R as a regular padlock for gates or toolboxes?
It is a dedicated safety lockout padlock and should be reserved for energy control under 1910.147. Mixing LOTO locks with general security use creates confusion during a lockout. Keep your lockout padlocks for LOTO only.
How many A1107R locks should I stock?
Plan at least one lock per authorized worker per simultaneous isolation point, plus spares for multi-point and group jobs. Keep extras and tags staged at a lockout station so a fresh lock is always at hand.
What else do I need to complete a LOTO kit with this lock?
Add lockout tagout tags for accountability, lockout hasps for group lockout, and device-specific lockouts such as cable lockouts and plug lockouts for the energy points you isolate.
How does the A1107R compare to other American Lock A1107 colors?
The lock format is the same across the A1107 series — color is the main difference and drives crew or department coding. Red is a common high-visibility default. Compare colors and other brands in the lockout padlocks collection and the wider lockout tagout range.

I love this particular lock. First it's metal and not some cheap plastic. When I lockout a circuit or machine or valve out in my trade. I feel it is securely locked out. I wish companies would go back to buying lockout tag out locks like this.his again. This is a good lock period!
