At Height Inc P4HYDRA Hydra Triple Attachment Pulley With Swivel Top

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. Rubber o-rings line the connection points to assist in holding carabiners tightly to avoid dangerous cross-loading. 

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.

Features and Benefits:

- 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
