Rock Exotica Hydra

Rock Exotica Hydra

Rock Exotica Hydra



COLOUR MAY VARY The Rock Exotica Hydra is a swivelling, triple attachment pulley, cleverly combining a three-point attachment rigging plate, an efficient swivel and a super smooth pulley. The Rock Exotica Hydra is ideal for use on a rope bridge or zipline. It also makes an excellent lanyard adjuster. The carabiner holes in the triple attachment top are rubber-lined to keep your carabiners positioned correctly (works best with Rock O oval carabiners). Every Rock Exotica Hydra pulley component is machined to be rope-friendly and built for strength - the Hydra is rated at 28kN and weighs only 159 g. Note that the Rock Exotica Hydra has no swinging side plates, so you can not mount it midline. Made in the USA.
