Asymmetrical taper gives stable placements in offset cracks 
Nuts with an offset taper protect cracks where normal nuts would not sit properly, such as flared cracks and peg scars. Use in combination with normal nuts to find security in almost any crack.

Grooved faces improve security in irregular rock
Wallnuts and Offsets have a groove machined into their faces, allowing them to sit better in irregular placements and on highly featured rock. This makes them more versatile across different rock types.

Color coded for easy size identification
The DMM protection range is colour coded on the anodised nut and shrink wrap for quick and easy size selection.

Allows placement in two orientations for increased versatility
Passive protection can be placed either side or face on, doubling the number of cracks any single piece can protect.

Passive protection works in wet and icy conditions
Passive protection works by jamming in constrictions to prevent falls. It is suitable for use in all conditions. Unlike active protection such as cams, passive protection can be used in wet or icy cracks, where friction is reduced.
