After observing how sport climbers were modifying their belay biners with rubber stoppers to prevent cross-loading with certain belay devices, DMM came up with a cleaner, simple, solution- the Rhino Screwgate Locking Carabiner. The horn prevents assisted locking belay devices rotating off the top bar and on to the spine reducing the risk of cross loading, it also works well with selected DMM pulleys.

A highly evolved and resilient creature. The horn prevents assisted locking belay devices rotating off the top bar and on to the spine reducing the risk of cross loading, it also works well with selected DMM pulleys. The Rhino works brilliantly with standard devices as well as lock assist devices. The full cross section of the top bar means greater wear resistance for belay rappelling. The wide top provides smooth operation in guide mode usage. The horn makes identification by feel on the rear gear loop possible. The shape of the clean nose design provides snag-free clipping and unclipping of ropes. The big burly top bar is contrasted with signature I-Beam construction (on the non-rope bearing surfaces) resulting in a total weight of 72g.

The DMM Rhino Carabiner provides a cleaner, simpler solution to prevent cross-loading than those clunky biners with rubber bungs. The horn on the spine prevents most locking belay devices from rotating off the top bar in order to reduce the risk of cross-loading. An I-Beam construction makes the Rhino incredibly strong for how little it weighs, and a full cross-section at the top bar gives greater wear resistance for smooth belays. A clean nose lets you take the belay off without any snags. The Rhino comes in the classic screwgate design for old-school climbers, a quicklock design that twists to unlock, or a locksafe design that offers the most secure locking mechanism out of the three.
