The Frontline LIS31S Combat Series Shock Absorbing Lanyard was developed to deliver performance, durability, and reliability for workers across all industries. Built from high-strength polyester with an internal shock absorber—eliminating the external shock pack—this single leg lanyard delivers a compact, lightweight fall arrest solution without ever compromising on safety.
At just 3 feet, the LIS31S is ideal for applications where a shorter lanyard reduces swing fall exposure or where working close to an anchor point is required. Internal shock absorption limits fall forces to 900 lbs or less, and built-in impact indicators provide an immediate visual cue after any fall event so compromised equipment is never returned to service.
Internal Shock Absorber
No bulky external shock pack—just a clean, lightweight design with 3' free fall shock absorption built directly into the lanyard body.
Single Leg with Snaphook Ends
Compact single leg configuration with snaphook ends for straightforward connection to a compatible anchor point or dorsal ring.
Impact Indicators
Visual indicators activate upon a fall event, providing an immediate and clear signal that the lanyard must be removed from service.
Economical Without Compromise
The Combat Series is Frontline's go-to value solution—built tough for everyday use without cutting corners on safety performance.
