Treetools will add the Rock Exotica Omni swivel pulley/block to the tree climbing catalogue over the next few days.The Omni is a high strength, alloy pulley (36 kN) with a swivel head. The swivel eliminates twisting of the rope in the rigging system. It is available in a single and double sheave configuration.
A unique feature on these pulleys is the button-activated mechanism which releases the side swing plate, allowing quick access to the sheave for mid-line attachment.
The swing plates on most other pulleys are secured by a carabiner which must be removed before the rope can be introduced.
This action increases the chance of dropping the pulley - problem solved with the Omni since the pulley can remain attached throughout the rope loading procedure.
