The Rescue Wristlets #1001210 from Capital Safety feature a rescue and retrieval "Y" design. The yoke wristlets choke off to victim's wrists during extraction. The steel D-ring in the center connects to rescue device lifeline. Yoke wristlets attached to a Y-lanyard are ideal for rescue and retrieval applications. They keep the user in an upright position and reduce the space needed to extract them. The wristlets meet or exceed all applicable industry standards including OSHA and ANSI. The carabiner shown in photo is not included.
