The Elk River 35477 Flex-NoPac Shock Absorbing Lanyard is a lanyard from Elk River, stocked at $104.88. This review restates what the product page documents, places it in its fall protection lane, and points to the ranked guides for the head-to-head field.
What the Product Page Documents
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 ā 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 ā 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 ā 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.

Frequently Asked Questions
How much does the Elk River 35477 Flex-NoPac Shock Absorbing Lanyard cost?

What does the Elk River 35477 Flex-NoPac Shock Absorbing Lanyard listing actually document?
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 ā the NoPac and Flex-NoPac lines are trusted on cā¦
What are the alternatives to the Elk River 35477 Flex-NoPac Shock Absorbing Lanyard?
The sibling lanyard options linked in this review, ranked head-to-head in the fall protection guides below ā start with the buyer's guides for the field view.
Does this fall protection gear meet ANSI/OSHA requirements?
Ratings live on the product label and listing ā we restate what's documented and never assign standards a listing doesn't claim. OSHA 1926 Subpart M sets when fall protection is required; ANSI Z359-series covers the equipment specs. Verify the stamped markings on arrival.
How do I calculate fall clearance for this equipment?
Sum free-fall distance, deceleration distance, harness stretch, and a safety margin below the working level ā every connector and extension in the system adds to the math. The manufacturer's instructions carry the exact figures for this component.
When does fall protection equipment get retired?
After ANY arrested fall (the whole connected system), on visible damage ā cuts, burns, deformation, corrosion, illegible labels ā or at the manufacturer's stated service life. User inspection before each use, competent-person inspection on your program's documented schedule.
Can I mix brands within a fall protection system?
Rated components generally interconnect, but manufacturer instructions govern ā some pairings (connector gate sizes, D-ring geometries) are explicitly restricted. When instructions conflict, the more restrictive one wins.
What inspection does this equipment need?
Before each use by the wearer: webbing, stitching, hardware, labels. Periodically by a competent person, documented, at least annually per most manufacturer instructions. No legible label = out of service.
Who counts as a competent person for fall protection?
Someone able to identify hazards and authorized to correct them ā OSHA's definition, designated by the employer. Inspection sign-off, rescue planning, and system selection sit with that role.
What's the rescue plan requirement?
OSHA expects prompt rescue capability wherever fall arrest is used ā suspension trauma sets in within minutes. A plan that starts with 'call 911' fails the promptness test; trauma straps and a rehearsed retrieval answer it.
Does this equipment have a shelf life?
Manufacturers set service life in their instructions ā commonly 5 years from first use for soft goods, indefinite-with-inspection for hardware. In-service condition governs; the dates are ceilings, not guarantees.
How should fall protection be stored?
Clean, dry, out of UV and chemicals, hanging rather than crushed. A gang box floor soaked in cutting oil is how webbing dies young.
What goes in a minimal compliant personal fall arrest kit?
Rated harness, shock-absorbing lanyard or SRL matched to the clearance, and an anchor connector rated for the structure ā plus trauma straps and the inspection habit. Kits bundle exactly this.
Are aftermarket accessories safe to add to a harness?
Only manufacturer-approved accessories at approved attachment points ā tool lanyards to designated loops, never to load-bearing D-rings unless rated for it. The instructions list what's allowed.
Fall restraint vs fall arrest ā which does this serve?
Restraint prevents reaching the edge; arrest catches a fall in progress and demands clearance and rescue planning. The listing states the intended use ā matching system to task is the employer's hazard assessment.
The Bottom Line
Rated 4.5/5 on documented spec, configuration, and value. The Elk River 35477 Flex-NoPac Shock Absorbing Lanyard does the job its listing describes ā the guides above tell you whether it's the right pick against the field.
