A compact DMM pulley paired with a prusik loop for hitch tending and small haul systems.
The DMM Pinto pulley prusik set combines a small, efficient pulley with a matching prusik loop, so you have the two pieces most climbers reach for when they build a hitch-tending setup or a quick mechanical advantage. It is a tidy way to add a pulley and hitch to a climbing kit in one purchase.
On a moving rope system the pulley sits below your hitch so you can pull slack through with one hand as you climb. The Pinto's side plates swing open to load the rope mid-line, and the prusik loop gives you a grab point you can set anywhere on the line. Together they make a clean, repeatable setup.
Off the climbing line, the same two pieces make a fast progress-capture point in a small mechanical advantage system: tensioning a pull line, lifting a hung limb a few inches, or snugging a tag line. Keep these setups light; heavy rigging belongs on gear built for those loads.
Check that the prusik cord diameter suits your host rope. A hitch cord that is too thin for the rope can grab too hard, and one that is too close in diameter may slip. Test any new combination low before you trust it at height.
Before each use, spin the sheave and confirm it turns freely, check the side plates for cracks or burrs, and look over the cord for glazing, cuts, and stiff or flattened spots near the hitch. Retire the cord at the first sign of heat damage. See more options in our hitch cord and split tails section.
Life-support gear must meet the applicable standard (ANSI Z133 and the manufacturer's instructions), be inspected before every climb, and be used only by trained climbers.

Mostly as a hitch-tending pulley under a friction hitch, and as a small pulley in light haul or tensioning systems.
Usually yes. Hitch cord wears from heat and abrasion and should be retired when it glazes, stiffens, or shows cuts, while the pulley lasts much longer with basic care.
