Pros & cons

Specifications

What this lanyard is for

Tethering heavier hand tools and power tools up to 15 lb where a screw-lock carabiner's manual-close security matters — a core piece of a dropped-object prevention plan alongside toe boards, debris netting, and barricaded work zones. It's ranked in our tool lanyards guide, which covers ANSI/ISEA 121, OSHA considerations, and how tool tethering fits into the broader fall protection equipment guide. Workers overhead should also wear a hard hat rated for the jobsite, ranked in our hard hats guide, and gloves suited to the work in our gloves guide.

Compatibility

The screw-lock carabiner clips to a harness D-ring, tool belt loop, or anchor point. Confirm your tool weighs 15 lb or less and has a suitable attachment point before relying on this lanyard — the opposite-end hardware isn't itemized in the summary description, so check the full Amazon listing for that detail. A ProFlex 7024 glove pairs well when handling heavier tethered tools, and gloves suited to the work are ranked in our gloves guide.

How this lanyard compares

The Squids 3100 and shock-absorbing 3100FX are lighter-duty fixed lanyards; the retractable Squids 3002 and 3001 use a reel instead of a fixed length. For a different attachment style, see the 3703 tool tail attachment or the 3714 three-pack. Every option lives in the tool lanyards collection, and connectors are covered in the carabiners & connectors collection. Pair a tethered tool with an Ergodyne Skullerz 8970 hard hat for the rest of the overhead-work loadout.

Safety note: a tool lanyard is a dropped-object control, not a personal fall arrest system component — it protects people below from a falling tool, not the worker from a fall. Match this lanyard's 15 lb rating to your tool's actual weight, confirm the tool has a suitable attachment point, and retire the lanyard if the carabiner or webbing show damage. Toe boards, debris netting, and barricading are covered in the fall protection equipment guide, and the full connector field lives in the carabiners & connectors collection.

Ordering FAQ

Where do I buy the Ergodyne Squids 3105, and is it available?

WC Safety holds no inventory — the purchase happens on Amazon. Open the linked listing for live price, availability, and delivery speed.

What does the 15 lb rating mean?

The lanyard is rated for a tethered tool weighing up to 15 lb — the highest confirmed capacity among the Squids tool lanyards we’ve reviewed. Match your specific tool’s weight to this rating before tethering it.

What is an aluminum screw-lock carabiner?

A carabiner with a threaded sleeve you screw closed manually after clipping in, rather than a spring-loaded or self-locking gate. It requires a deliberate action to open, similar in principle to a locking carabiner but with a different mechanism.

How is this different from the Squids 3100FX?

The 3100FX is shock-absorbing and rated for 10 lb with a self-locking spring carabiner; this 3105 is rated for 15 lb with an aluminum screw-lock carabiner and doesn’t specify a shock-absorbing element.

What's at the other end of the lanyard?

The listing’s summary description doesn’t itemize the opposite-end attachment — check the full Amazon listing or Ergodyne’s spec sheet for the exact loop or hardware style before ordering if that detail matters for your setup.

Why choose a screw-lock carabiner over a self-locking one?

A screw-lock gate stays closed until you manually unscrew it, which some crews prefer for tools that shouldn’t come loose under any circumstance — it’s slower to open and close than a spring-loaded self-locking gate.

What tools weigh close to 15 lb?

Check your specific tool’s spec sheet or weigh it directly — heavier cordless tools and some power tools fall in this range, but always confirm before tethering rather than estimating.

Is this ANSI/ISEA 121 rated?

Ergodyne publishes the certification — edition and rated capacity — on its own product page, and this page's callout states it as verified against that source. Retail marketplace summaries may omit it; the manufacturer's spec sheet and the label on the tether itself are the authority.

How do I inspect this before use?

Check the lanyard material for cuts, fraying, or UV damage, and confirm the screw-lock carabiner’s threaded sleeve turns smoothly and seats fully closed. Retire if the carabiner doesn’t lock securely or the material is damaged.

Does this replace toe boards or barricades below the work area?

No — tethering reduces the chance a tool falls, but it doesn’t replace other dropped-object controls like toe boards, debris netting, or barricading the area below overhead work per your site’s hazard assessment.

Can I use this for power tools specifically?

If your power tool has a suitable attachment point and weighs 15 lb or less, this lanyard’s rated capacity can accommodate it — confirm the tool’s actual weight and attachment compatibility first.

How do I reorder for a crew?

Reorder from this page — the listing and its linked Amazon ASIN stay constant, so equipping every tool on a crew takes seconds.
