The backbone of every trad rack.

Despite their simple appearance, Wallnuts are highly featured pieces of climbing hardware. Different alloy is used for each size - smaller Wallnuts are made from a harder alloy to prevent shearing, while larger sizes are softer so they can bite into placements. Larger Wallnuts feature hollow construction to reduce weight.

Wallnuts can be placed in two different orientations, allowing a single nut to cover a range of cracks. They are tapered across both their face and sides, helping them sit better in cracks that are rarely parallel sided. Grooved faces reduce weight, help the nut seat better in cracks, improve security in shallow placements, and resist lifting out when a leader moves past them.

Wallnuts are mounted on wires that are stiff enough to allow overhead placements, while flexible enough to reduce the chance of lifting out. They are colour coded to correspond with the rest of our protection range, and to give quick and easy selection of the correct size from your harness.

Wallnuts are the basis on which to build a comprehensive climbing rack. Complemented by other, more specialised pieces of protection, they are guaranteed to be the most regularly used piece of protection on your harness.


Curved taper gives stable placements and resists lifting out

A Wallnut's curving taper fits a wide variety of cracks in different rock types. Their design creates three points of contact between the nut and rock in a placement, giving stable placements that resist lifting out.

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.

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.

Colour 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.

Go to Nuts

I have a double set of these and consider them essential to any trad rack, have tried lots of different brands when using friends racks but always prefer how the wallnuts fit, and equally as important come out. Never got one stuck so far.


These seem to fit everywhere, especially the number 3. I prefer the shape to wild country.

Always in my kit

Every time I go on rock wall I have them, even for sport climbing incase the bolts are too far away. The colors change everything also, game-changer for me !
