Description

Details

Spring lock blocks are popular among riggers for their high strength-to-weight ratio and quick-twist rope access. Solid aluminum-alloy cheek plates, bushing, and sheave are supported by stainless-steel axles. For those concerned about aluminum not withstanding the punishment of steel, we have no record of a fracture complaint in 3 years of production. Spring lock blocks have broad cheek plates to protect running lines, and large sheaves to minimize bend in rigging lines (providing 4:1 up to 9:1 ratios).

Very nice block, We use it with 5/8 bull rope to redirect the pull with our 277 CAT. Yes, I can pull around corners. ;-) (Posted on 6/29/2014)
Must Have... Review by Will

Sweet, sweet block. Easy to open, easy to close, smooth edges, and you can bomb pretty much anything in to it. This is the one I pull out when I have big logs that need to be rigged down via negative rigging. (Posted on 5/17/2014)
