The APEX LIMB-O and LIMB-O LOK are built to handle jobs where rigging must account for significant loads and high impact force potential.

Designed with a very high strength-to-weight ratio, these robust opening blocks provide enhanced friction for positive rigging scenarios. The LIMB-O LOK also features a locking sheave that helps reduce force for safer negative rigging.
