Description
4-5/8 in. sheave, up to 3/4 in. rope capacity, weighs 7.7 lbs., 4.4 ton working load limit. Green sheave (3/4 in. rope capacity) for easy identification. 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).
- ISC's largest block, this very large pulley has an 8,800 lbs. working load limit for the largest rigging jobs
- Made from thick aluminum alloy for strength without being too heavy to manage
- Broad side plates protect running ropes from damage during rigging and the wide sheave minimizes the bend in your line
- The spring lock is simple and easy to use even when wearing gloves
- WLL: 40kN (8,800 lbf) MBS: 200kN (45,000 lbf) CE Approved
