A durable double-lock buckle makes for easy anchoring, while high-stretch elastic reduces jarring on the worker in the event of a drop. Tested and complies with ANSI/ISEA 121-2018 for dropped object prevention.Compatible with all hard hats, this safety lanyard can be easily connected via the accessory slot or suspension. It can also be used for tethering hand tools or other small gear. Ideal for construction, telecom, oil and gas, power generation, utilities, manufacturing, municipalities and scaffolding. Thread the open end of the lanyard through the hard hat accessory slot or suspension and back through the clamp, closing tightly for a secure connection. To anchor, clip the buckle end around a reliable connection point on the worker fall protection harness, safety vest strap, etc..
