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. Spring lock blocks have broad cheek plates to protect running lines and large sheaves to minimize bend in rigging lines.
