The CMI ProKnot™ Arborist Rigging Device

We've married a pair of our ascenders—unmatched in the world for their quality and durability—and added a heavy-duty arborist rope to create a rigging device that's versatile and tough enough to quickly match your most challenging rigging demands. The body is milled from a single piece of aluminum for an exceptional stregth-to-weight ratio.

The cams, of course, are covered by our exclusive lifetime wear-out guarantee—if you can wear them out, we'll replace them. Free. Forever!
