Ergodyne Squids 3100F(x) Shock-Absorbing Tool Lanyard, 10 lb

The 3100F(x) itself is third-party certified to ANSI/ISEA 121-2023 and rated to 10 lb with a 2:1 safety factor per Ergodyne's own product page — distributor listings that still show the 2018 edition are out of date; the manufacturer is the authority.

Standard and capacity: Ergodyne rates the Squids 3100F(x) at a 10 lb / 4.5 kg maximum tool weight. Confirm the ANSI/ISEA 121 edition printed on the label for the unit you receive — Ergodyne certifies different Squids models to different editions of the standard.

A shock absorbing tool lanyard rated for 10 lb — Ergodyne Squids 3100FX

A dropped tool that hits the end of its tether still delivers a jolt, and a shock absorbing tool lanyard softens that impact. The Ergodyne Squids 3100FX pairs a self-locking carabiner and an adjustable loop end with a shock-absorbing element, confirmed for a 10 lb tool weight capacity.

Shoppers searching a tool bungee lanyard for that stretch-and-absorb feel, a heavy duty tool lanyard with a confirmed weight rating, or an ergodyne 3100 variant with shock absorption, land on the 3100FX.

Pros & cons

Specifications

What this lanyard is for

Tethering a tool up to 10 lb where the shock-absorbing element and self-locking carabiner add a margin over the plain Squids 3100 — 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 self-locking carabiner clips to a harness D-ring, tool belt loop, or anchor point; the loop end wraps around a tool's handle or existing attachment point. Confirm your tool weighs 10 lb or less and has a suitable loop or D-ring attachment before relying on this lanyard. A full brim safety helmet is a common pairing when overhead tool tethering is part of the site's dropped-object plan.

How this lanyard compares

The standard Squids 3100 is the same carabiner-and-loop design without the shock-absorbing element, self-locking carabiner, or the self-locking carabiner. For a retractable mechanism instead of a fixed length, see the Squids 3001 or Squids 3002. Ergodyne also makes the Squids 3105, the 3703 tool tail attachment for tools without a built-in loop, and the 3714 three-pack for equipping several tools at once. Every option lives in the tool lanyards collection. Pair a tethered tool with a rated Ergodyne Skullerz 8970 hard hat and ProFlex 7024 gloves for the rest of the jobsite 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 10 lb rating to your tool's actual weight, confirm the tool has a suitable attachment point, and retire the lanyard if the carabiner, loop, or shock-absorbing element show damage or prior deployment. Barricading the area below overhead work is covered in our fall protection equipment guide.

Ordering FAQ

Where do I buy the Ergodyne Squids 3100FX, 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 10 lb rating mean?

The lanyard is rated for a tethered tool weighing up to 10 lb. Match your specific tool’s weight to this rating before tethering it — heavier tools need a lanyard rated for that weight instead.

What does “shock absorbing” add over the plain Squids 3100?

A shock-absorbing element in the lanyard that softens the jolt transmitted through the tether if the tool drops and the lanyard reaches full extension — the plain 3100 has no equivalent shock-absorbing component.

Is the carabiner self-locking?

Yes — the 3100FX’s carabiner is self-locking, an upgrade over a standard spring-gate carabiner, reducing the chance it opens accidentally under snag load.

What's at the other end?

An adjustable loop end that wraps around the tool’s handle, D-ring, or existing attachment point per Ergodyne’s instructions.

Is this retractable?

No — this is a fixed-length lanyard with a shock-absorbing element, not a retractable reel. See Ergodyne’s Squids 3001 or 3002 for retractable versions in the same line.

How is this different from the standard Squids 3100?

Both share the carabiner-and-loop-end design; this 3100FX adds a shock-absorbing element and a self-locking carabiner, plus a confirmed 10 lb capacity, while the standard Squids 3100 uses the same shock-absorbing tubular nylon webbing and is itself third-party certified to ANSI/ISEA 121-2023 at 10 lb / 4.5 kg — the F(x) difference is the dedicated shock-absorbing element and the self-locking carabiner, not the rating.

What tools weigh close to 10 lb?

Check your specific tool’s spec sheet or weigh it directly — many hand tools, some cordless drills, and similar equipment 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, confirm the self-locking carabiner gate opens, closes, and locks fully, check the loop end’s cinch mechanism, and inspect the shock-absorbing element for signs of prior deployment. Retire if any component 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.

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.
