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..

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..
The DMM protection range is colour coded for quick and easy size selection. Colours are co-ordinated across passive and active protection, for quick selection of alternatives if your first choice doesn’t fit..
