Harken Apex Limb-O Lok

Big Loads. Big MechanicalAdvantage.

The APEX LIMB-O and LIMB-O LOK are built to handle jobs where rigging must account for significant loads with considerable impact force potential. Designed with a very high strength to weight ratio, these robust opening blocks offer enhanced friction for positive rigging scenarios, while the Limb-O LOK’s locking sheave provides the added benefit of force reduction for safer negative rigging.
