This is one of the original CMI rescue pulleys that set the standard for lightweight, compact, yet functional rescue pulleys 50 years ago. Now featuring stainless steel axles on all models, they are built around either glass-filled Celcon or aluminum sheaves and employ either a sintered bronze bushing or sealed needle bearing. All models accept up to 5/8″ diameter ropes and feature our now famous “wide skirt” sideplate design for maximum rope protection. These are the most versatile rescue pulleys available and their lightweight, compact design makes them a pleasure to carry. A step up in strength and durability with Black anodized aluminum sideplates, 2 3/8″ aluminum sheave, bushing, and stainless steel axle.
