Hydra Pulley
The Rock Exotica Hydra pulley combines a great pulley, efficient swivel, and rigging plate all into one unit. The Hydra shines as a rolling attachment point on rope bridge harnesses, where the swivel eliminates twisting of the climbing line. Other uses include running the hydra to tend your friction hitch on a lanyard, using it to tend a friction hitch on a climb line, and more.
The carabiner holes in the triple attachment top are rubber-lined to keep your carabiners positioned correctly (works best with RockO oval carabiners). Every component of the Hydra pulley is machined to be rope-friendly, and built for strength - the Hydra is rated at 28kN and weighs only 5.6 oz.
Note that the Hydra has no swinging sideplates, so it can't be installed midline.

Not for me
by Tyler
My intention was to use as primary bridge connection. The pulley ended up being too efficient and made it difficult to position sideways without completely falling over until it reached the end of my bridge. Well made product. Maybe I could use it for something else but it just sits in a box now
