DMM Hitch Climber Eccentric Pulley

The DMM Hitch Climber pulley is an eccentric hitch-tending pulley that sits under your friction hitch and lets you pull slack through smoothly. Its offset attachment points keep the hitch cord eyes apart and the bridge connection in line, so the hitch stays dressed and releases cleanly.

Why the eccentric shape matters

A plain pulley under a hitch works, but the hitch cord eyes and the bridge connector tend to fight for space. The Hitch Climber gives each its own hole, with the upper holes for the eyes of your hitch cord and the lower hole for the connector to your bridge. That keeps the hitch tied the same way every time and makes it easier to break and reset.

Pull the tail of your climb line through the sheave as you go up and the hitch follows along without you holding it.

Many climbers keep the same pulley on their system for years, replacing the hitch cord around it as it wears. That makes the Hitch Climber a good long-term investment, as long as you inspect it and keep the sheave clean.

Inspect the sheave, bushing and holes for wear and grooving, and retire the pulley if it is damaged.

Setup notes

Use connectors that fit the holes and sit in the right orientation; the DMM Hitch Climber Kit pairs the pulley with matched carabiners. Match your hitch cord to your climb line and test on the ground.

Anything you hang your life on must meet the applicable standard, be used per the manufacturer's instructions and ANSI Z133, and be inspected before every climb by a trained user.

The color options are also useful on crews where several climbers share a truck. Each climber can run their own color, so systems do not get mixed up at the end of the day.
