Rock Exotica Omni-Block 1.5" Pulley

The Rock Exotica Omni-Block 1.5" is a precision-machined swivel pulley designed to reduce overall vertical height in your rigging system while keeping loads moving smoothly. The integrated swivel allows the pulley to rotate freely under load, eliminating rope twist and keeping your system running clean — a feature that makes a real difference when you're managing heavy pieces from the top of a tree.

A double locking mechanism maximizes safety, and the large top hole with rounded edges accommodates both hard connections (carabiners) and textile connections (slings, cordage). Rock Exotica's signature precision machining and cutting-edge design make this one of the most capable pulleys in its class.
