Sterling has teamed up the innovative F4 escape device with the Tech Extension Lanyard to offer a complete escape device/attachment point for use in personal escape situations. The Tech Extension Lanyard is constructed out of a hollow-braid Technora cord for superior heat resistance and offered in a 7″ length and 9″ length. The Tech Extension is used to help extend the F4, away from the harness.The lanyard is sewn directly to the F4, eliminating the need for a girth hitch. The F4’s sleek, lightweight design is compatible with Sterling’s 7.5 mm to 9 mm escape ropes. The auto-locking feature adds security and confidence for a hands free exit of the structure. Engineered to allow easy horizontal movement. The low profile shape will pack easily in many bag styles. Color: Red. Made in USA.
