What the Product Page Documents

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

The Elk River 35477 Flex-NoPac Shock Absorbing Lanyard is an OSHA 1926.502 and ANSI Z359.13 compliant energy absorbing lanyard from Elk River's popular NoPac series. Elk River has manufactured fall protection equipment in Roanoke, Virginia since 1966 — the NoPac and Flex-NoPac lines are trusted on commercial construction, bridge work, tower climbing, and industrial maintenance job sites across North America. Model 35477 features 6 ft fixed length with 1-1/2 in. polyester web and Elk River's proprietary Z-hardware connectors.

The Z-snap and Z-rebar hook system uses a double-locking mechanism engineered to prevent accidental opening during normal work movements — the gate requires two deliberate actions to open, exceeding OSHA's self-closing, self-locking requirement under 1926.502(d)(2)(vi). The NoPac shock absorber is rated to limit maximum arresting force to 900 lb or less, meeting ANSI Z359.13 requirements for workers up to 310 lb.

Elk River's Z-hook system includes two primary connector styles: the Z-snaphook and the Z-rebarhook. The Z-snaphook is a self-locking snap hook with a double-action gate suitable for anchor rings, D-rings, and structural connectors. The Z-rebarhook is specifically designed to grip vertical and horizontal rebar, scaffold pipe, and structural members where a snap hook cannot properly seat — the hook's geometry wraps securely around round stock without the risk of roll-out that can occur with standard snap hooks on non-flat surfaces.

Where It Earns Its Slot

The 35477 is Elk River's single-leg elastic: a Flex-NoPac lanyard whose bungee web retracts short at rest and pays out to working length as you move — no external absorber pack, nothing dangling at boot level. It aims at the daily nuisances that make workers resent lanyards: slack underfoot and packs that snag.

The 35416 Twin-Leg is its Y-leg sibling for jobs that traverse; the wider market's packed lanyards trade its slim profile for inspectable absorbers. Spec territory is standard for the class — the difference is what the lanyard does during the 99.9% of the day when nobody is falling.

Honest Limits

Elastic web hides damage better than flat web: inspect it stretched under load, not slack, and measure against original length — permanent elongation is deployment evidence. Clearance math uses the FULL extended length plus deployment plus stretch plus height (fall-clearance guide); the retracted resting length is a comfort figure, never a planning one.

The Bottom Line

Rated 4.5/5. For single-anchor work where snag and slack are the daily enemies, the 35477 is a clean, livable choice that arrests like the packed lanyards it out-comforts. Traverse jobs step up to the 35416; inspection-heavy programs may prefer a windowed pack they can see into.

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

Does the elastic retraction shorten my fall?

No — plan on the fully extended working length. The retraction is ergonomics: less slack underfoot and less snag surface while you work. In an arrest the lanyard is at length, and the clearance calculation must already have assumed it.

How is a bungee lanyard inspected properly?

Under tension: stretch each section and examine the web loaded, where elastic sheathing can no longer hide cut strands or glazing. Compare overall length against spec — permanent elongation means the energy absorption has worked once already, and once is retirement.

What makes Flex-NoPac different from a tear-pack?

The absorption lives in the webbing, not in an external pack — so there is no pack to snag, and no pack window to inspect either. You gain profile and lose visual access; programs choose by which failure mode worries them more.

When is single-leg the wrong choice?

Whenever the job moves anchor to anchor: each transition on a single leg is a moment of total disconnection. That is the 35416's brief — one leg stays clipped while the other moves. Buy by how the work moves, not by lanyard weight.
