Rock Exotica P4 Hydra Block

Rock Exotica P4 Hydra Block

The HYDRA is a triple attachment pulley which features a swivel-top connection to facilitate the pulley's use on the saddle bridge, and for use in climbing systems.

Any tool for arborists needs to be lightweight, durable and serve a variety of functions. The HYDRA fits that description by providing the functionality of a pulley with a rigplate. The HYDRA’s swivel top offers three connection points lined with rubber o-rings to grip carabiners tightly. These connection points were specifically designed for the rockO carabiner to avoid dangerous cross-loading.

The most simple use of the HYDRA pulley is on the rope bridge of the saddle, but it can be used in a variety of advanced ways. The Hydra is used in ascent systems, lanyard systems, fliplines, or as a redirect as shown below. In any configuration, the use of the HYDRA is greatly enhanced by the flexibility to add multiple connections and rotate when needed.

• Combines a pulley, rigging plate and swivel all in one compact piece of equipment
• Use on the saddle bridge, as a lanyard adjuster or in your climbing system
• Eliminates twisting of the climbing line when used as a rolling attachment point on the saddle bridge
• Rubber grommet-lined attachment points hold carabiners snugly to help prevent cross-loading
• Pulley sheave uses high-efficiency bearing for smooth operation
• Pulley body is machined from solid aluminum to increase strength and decrease weight
