The ShockWave 2 Shock Absorbing Lanyards are extra-stretchy for complete freedom of movement. Lanyards expand from 4.5 feet to 6 feet in reaction to your movements, reducing the risk of tripping hazards. Double leg 100% tie off style allows wearer to remain safely connected at all times for extra security. The self-locking snap hooks at both ends are easy to use. Abrasion-resistant nylon tubular webbing is durable and long-lasting and limits the arresting force to 900 pounds or less. The impact indicator allows you to easily see if the lanyard has been deployed in a fall. Meets or exceeds all industry safety standards, including OSHA, ANSI and ANSI Z359 requirements.
