Each part of the Hydra is machined to be rope - friendly and built tough. It's rated at 28kN and weighs only 159 g. Note that it doesn't have swinging sideplates, so it can't be installed mid - line. It's proudly made in the USA. Additional features include being a great zipline or skyline pulley, an efficient choice for rope bridge harnesses. The three - point attachment rigging plate swivels to reduce rope twisting and tangles. The attachment points on the rigging plate have internal rubber grommets to control carabiner movement and minimize cross - loading. It's designed to work well with the Rock Exotica Rock O oval - shaped carabiner and is CNC 4 - axis machined from T6 aluminum.

Using the Rock Exotica Hydra is easy. First, if you're using it for a rope bridge or zipline, attach it to the main rope using the appropriate carabiners, preferably the Rock Exotica Rock O oval - shaped ones. Make sure the carabiners fit well into the rubber - lined holes at the triple attachment top. For use as a lanyard adjuster, simply connect it to your lanyard. Remember, since it doesn't have swinging sideplates, you can't install it mid - line. When it comes to maintenance, regularly check the rubber grommets and the sheave for any signs of wear. Keep it clean and dry to prevent rust. If you notice any significant damage or wear, it's best to replace the pulley for safety reasons.
