12mm Offset D

The DMM 12mm Offset D is a locking steel karabiner that is ideal for use in commercial environments, such as work positioning or in outdoor adventure parks and education centres. An Offset D connector takes the spinal loading strength of a D-shaped back but extends the basket at one end to maximize gate opening and overall size without compromising ergonomics and weight. Cold forged from 12mm bar, the strengths achieved in testing exceed 45kN and it is first choice in applications requiring stronger connectors in their systems.

12mm Klettersteig

The DMM 12mm Klettersteig is a steel carabiner that offers high levels of strength whilst combining a large gate opening so its easy to clip on steel cables for use on a Via Ferrata. The Klettersteig shape takes the strength and volume increases of an Offset D and then extends them even further to give a high volume, super-strong connector. The Klettersteig’s wide gate opening makes it particularly suitable for clipping oversized items, or simply allows ease of use in more normal situations.

Rhino

The DMM Rhino karabiner is not restricted to assisted locking belay devices: it works brilliantly with standard devices. The full cross section of the top bar means greater wear resistance, and smooth operation in guide mode usage. The horn makes identification by feel on the rear gear loop easier, and the clean nose design provides snag-free loading and unloading of ropes. The big burly top bar is contrasted by our signature I-Beam construction on the non-rope bearing surfaces resulting in a total weight of 72g.

Ceros

The horn on the spine of the karabiner helps prevent assisted braking devices from jumping onto the spine.
