A matched hitch-tending pulley and connector set for building a friction hitch system.
The DMM Hitch Climber kit bundles the Hitch Climber pulley with matching DMM carabiners so you can build a tended friction hitch system in one purchase. The hitch climber pulley keeps your hitch dressed and lets you pull slack through smoothly as you climb.
A friction hitch on its own works, but it needs a hand to tend it. With a hitch climber pulley under the hitch, you can pull slack through the pulley as you advance, and the hitch follows along without you holding it. The pulley also keeps the two eyes of your hitch cord apart, which helps the hitch release and reset consistently.
Buying the kit saves you from matching connectors yourself. The carabiners are chosen to fit the pulley's holes and to sit in the right orientation.
Matched connectors also help with inspection, because you are always checking the same parts in the same positions. That consistency matters when you build your system quickly at the base of the tree every morning.
Tie the hitch with a cord suited to your rope diameter, clip the eyes to the upper holes, and connect the lower hole to your bridge per DMM's instructions. Test the system low to the ground and make sure the hitch grabs when you let go. Add an eye-and-eye cord from our eye-and-eye prusiks range if you need one.
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.
If you already own a Hitch Climber pulley, you may only need the carabiners. Check the kit contents against your existing gear before buying, and replace any connector that shows wear, grooving or a sticky gate.

Specs are from the manufacturer's published figures where available. Confirm against the product listing before you buy.
Check the listing for the specific kit you buy. Many climbers buy the cord separately so they can match diameter and material to their climb line.
It is one of the most common ways to learn a tended friction hitch. Learn it from a qualified trainer and test it on the ground first.
