Rock Exotica Omni-Block 2.6

The Rock Exotica Omni-Block 2.6 is a single pulley with a 2.6 inch sheave and a swiveling body, so it lines up with the load wherever the rope goes. The larger sheave runs efficiently and treats rope gently, which makes it a favorite for redirects and haul systems.

Why a bigger sheave helps

Rope loses efficiency and wears faster when it bends tightly over a small wheel. A 2.6 inch sheave gives a gentler bend, so a haul system runs smoother and your rope lasts longer. The swivel lets the pulley turn to face the load, so lines stay untwisted even when the pull angle changes.

Arborists use it as a redirect for a pull line, in a mechanical advantage system, or as part of a rescue kit. Check Rock Exotica's published ratings and rope range before planning a setup, and keep loads within the weakest link.

The opening side plates mean you can load the pulley onto a line that is already rigged, so you can add a redirect partway through a job without untying anything. It is a small detail that saves real time when a ground worker needs to change a pull angle quickly.

Inspection

Check that the swivel turns freely, spin the sheave, and look for cracks or wear on the side plates and attachment hole. See more pulleys in our rigging pulleys section.

Rigging forces are dynamic and can be several times the weight of the piece. Follow the manufacturer's ratings and ANSI Z133, inspect every component before the job, and keep rigging work to trained crews.
