DOUBLE CAMMING PULLEY At last the American leader in Rescue Pulleys and Ascenders has combined the two into the easy to use UP-LIFT Pulley.
The 3" (76mm) Sheave diameter increases mechanical efficiency and the color coding of the swing side plates make rigging simple. Cam may be locked open or retracted for quick remote release by the attached cord.
The cam comes with a lifetime guarantee, if the cam wears out CMI will repair or replace it.
UPLIFT pulleys are designed to accept 3/8" to 1/2" (10 to 12.5mm) ropes. The companion double pulley is built to the same specifications.
