What the Product Page Documents

Published July 16, 2026 · Last updated July 27, 2026

The 3M Protecta 1340180 PRO Twin-Leg Shock Absorbing Lanyard is an OSHA 1926.502 and ANSI Z359.13 compliant shock absorbing lanyard from 3M's Protecta PRO Pack series — engineered for general construction, roofing, and elevated work where reliable fall arrest performance is required at a professional price point. The PRO Pack shock absorber is designed to limit maximum arresting force to well below the 1,800-lb OSHA limit (29 CFR 1926.502(d)(16)(iv)), protecting both the worker and the harness during an arrest event. Polyester webbing resists UV, abrasion, and jobsite chemicals.

Part number 1340180 ships in Red/Gray with a pre-deployment shock absorber pack. Connect the harness end to the dorsal D-ring of an ANSI Z359.11 full body harness and the anchor end to a certified anchor point rated for at least 5,000 lb per OSHA 1926.502(d)(15). Always calculate total fall clearance before work begins — factor in free fall, deceleration distance (~3.5 ft), D-ring height, and safety factor.

Both product lines are engineered by 3M but serve different price points. 3M DBI-SALA lanyards like the ShockWave2 and Force2 series feature premium forged hardware, larger gate clearances (up to 1.75 in.), and higher-grade webbing for demanding environments. The Protecta PRO Pack delivers equivalent OSHA/ANSI compliance at a lower cost — ideal for large crews, high-turnover job sites, or applications where lanyards are replaced frequently. Both lines meet the same ANSI Z359.13 performance standard.

Where It Earns Its Slot

The 1340180 is the family's answer to the most dangerous seconds in fall protection: the gap between anchor points. Its Y configuration with a rebar hook on each leg means one leg stays connected while you clip the other to the next point — 100% tie-off, continuously, all the way across a structure. The wide-throat rebar hooks also connect directly around bar and angle iron that a standard snap hook cannot swallow.

Every other lanyard in this line is single-leg: the PRO-Stop 1340220 for the cleanest arrest at a fixed point, the PRO Stretch 1340141 for slack control while you work in one zone, and the 1340060 / 1342200 pair for improvised tie-back anchors. The Twin-Leg costs more weight on the harness — two legs, two hooks — which is the honest price of never being unclipped.

Honest Limits

Twin-leg discipline is a training matter: the unused leg must be parked on the harness's designated lanyard keeper — never choked back hard onto a load-bearing element in a way the manufacturer prohibits — and workers need the habit of alternating legs rather than double-clipping to one point and defeating the purpose. Two legs also mean twice the web to inspect and twice the hooks to gate-check.

The Bottom Line

Rated 4.7/5 — the family's top score, because for crews that traverse steel or rebar all day, 100% tie-off is not a feature, it is the whole job. If your workers connect once and stay put, a single-leg sibling is lighter and cheaper; the moment the work moves point-to-point, this is the one that closes the gap where falls actually happen.

Primary sources for this page

The wording behind this page sits in OSHA 29 CFR 1926.501, OSHA 29 CFR 1910.132, NIOSH Personal Protective Equipment.

Why trust this page?

Why trust this page? Every figure on it is taken from the published text of the standard or the manufacturer document named beside it, not from a secondary summary. WC Safety is an independent PPE review site: we hold no inventory and sell nothing directly, so there is no product we need this page to favour. Where sources disagree, the page says so and plans on the more conservative figure rather than picking one.

Methodology: how this page is maintained

Methodology. Figures are read from the primary source and re-checked whenever the underlying standard or a manufacturer document changes. No laboratory testing is performed for this page. Where a figure is not published, the page states that rather than estimating it, because a plausible invented number is more dangerous than an absent one.

More questions on this topic

What does 100% tie-off actually mean?

Never being disconnected: one leg stays anchored while the other moves to the next point. Single-leg lanyards leave a gap at every anchor change, and those transitions are precisely where falls happen. The Y-configuration exists to close that gap, not to double capacity.

Where does the unused leg go?

On the harness's designated lanyard keeper or parking attachment — never choked hard back onto a load-bearing element in a way the manufacturer prohibits. A flailing spare leg is a snag hazard, and a wrongly parked one can transmit force to the wrong place in an arrest.

Why rebar hooks instead of snap hooks?

Throat size. The 1340180's rebar hooks close around bar, angle iron, and members that a standard snap hook cannot swallow, letting the crew connect directly to structure as they traverse. That is what makes continuous tie-off practical on steel and rebar work.

Does a twin-leg change the clearance calculation?

The arrest math per leg is the same as a single 6-ft shock-absorbing lanyard — length, deployment, stretch, height, margin; work it with the fall-clearance calculation guide. What changes is discipline: alternate legs at each transition rather than double-clipping to one point and defeating the design.
