LIS61SDL Oil and Gas 6 ft Single Leg Lanyard with Snap Hooks, 2-Pack
The Frontline LIS61SDL is a 6 ft single leg shock absorbing lanyard from the Frontline derrick line - lanyards built specifically for oil and gas service, where drilling fluid, dust, and hydrocarbons retire standard gear early. Snaphook ends connect harness to anchorage, with the energy absorber in line.
Hardware is alloy steel with a silver galvanized finish rated to 5,000 lbs; the 1.2 in polyester webbing carries a 6,000 lb breaking strength. At about 3 lbs it is a lightweight, highly durable build, made to ANSI Z359.13 and aligning with OSHA 1926 and 1910, with Intertek testing on the derrick lanyard models.
Who Needs This Product
This product is a fall arrest connecting device built for derrick and oil and gas service - environments where drilling fluid, dust, and hydrocarbons destroy standard webbing. Derrickhands and rig crews pair it with a derrick or oil and gas harness; you still need a rated anchorage to complete the system.
Features
Built for the rig
Purpose-designed for oil and gas service conditions: mud, dust, water, hydrocarbons.
Silver galvanized hardware
Corrosion-resistant finish on the alloy steel snap hooks.
6 ft shock absorption
In-line energy absorber limits arrest forces per Z359.13.
Light and durable
About 3 lbs of lanyard built to outlast standard webbing in rig service.
Snaphook ends
Double-action snap hooks at harness and anchor ends.
Derrick line family
Pairs with the LIS62RDL twin leg and the Frontline derrick harnesses.

Clearance is everything with a shock absorbing lanyard. The energy absorber needs room to deploy below the work surface - account for free fall distance, absorber elongation, harness stretch, and worker height before trusting any tie-off point. Run the Fall Protection Calculator below, and keep the free fall within the limits in the Frontline manual.
Compliance Standards
ANSI Z359.13
American National Standard for personal energy absorbers and energy absorbing lanyards. Intertek test report linked in Submittals.
OSHA 29 CFR 1926.502

OSHA 29 CFR 1910.140
General industry personal fall protection system requirements.
Typical Applications
How to Use the LIS61SDL
Follow the manufacturer's manual. The sequence below is an overview only.
- Inspect. Check webbing, absorber, stitching, and hooks before each use - oil and gas service demands it.
- Verify clearance. Confirm total fall clearance including absorber deployment - run the calculator below.
- Connect to the harness. Attach the harness end to the dorsal D-ring (or per your derrick harness configuration and the manual).
- Connect to the anchor. Attach to a rated anchorage connector at or above the D-ring where possible.
- Check the gates. Confirm every hook is fully closed and locked.
- Limit free fall. Work so free fall stays within the limits in the Frontline manual.
Inspection and Retirement
Inspect before each use, with a documented competent-person inspection at least every 6 months. Pull the equipment from service for any of the conditions below.
- Webbing: cuts, fraying, abrasion, burns, chemical damage, or stiffness.
- Energy absorber: deployment, torn cover, or a tripped impact indicator.
- Stitching: broken, pulled, or abraded threads at terminations.
- Hooks: deformation, cracks, corrosion, or gates that fail to close and lock.
- Markings: labels must be present and legible.
Retire the lanyard immediately after any fall arrest event - the energy absorber is single-use - or if any inspection point fails. Destroy retired equipment so it cannot return to service.
