DMM Revolver Rig Locksafe Carabiner

The DMM Revolver Rig is a Locksafe auto-locking carabiner with a pulley wheel built into the basket. It cuts friction where rope turns around the carabiner, which makes it useful for redirects, mechanical advantage systems and tidy climbing setups.

Where the Revolver Rig fits

Every time rope turns around a plain carabiner, it loses energy to friction. The Revolver's wheel lets the rope roll instead of slide, so a redirect or a simple 3:1 haul system runs noticeably easier. Climbers use them on the bridge, at redirects in the canopy, and in light pulley systems for pulling tension or tensioning lines.

The Locksafe gate is DMM's auto-locking design: it closes and locks on its own, and opening it takes a deliberate sequence. That gives you a secure connection without having to remember to spin a screw gate. Browse more auto-locking carabiners for other shapes and materials.

Because the wheel is part of the carabiner, the setup stays compact on your saddle and there is one less piece of hardware to clip, lose or forget.

Use and care

Load the carabiner along its major axis and keep the wheel side where the rope runs. Do not side-load it over a limb or across hardware. Rinse grit out of the wheel and gate after dirty jobs and let it dry.

Check that the gate snaps shut and locks fully every time. Retire any carabiner that has been dropped onto a hard surface from height or shows cracks or deep grooves. Life-support gear must meet the applicable standard, be used per ANSI Z133 and the manufacturer's instructions, and be inspected before every climb by a trained user.
