DMM Mantis Belay Device

A modern take on the classic belay device - compact and lightweight, it will work across a wide range of ropes. Ideal for indoor wall use and cragging

If you are looking for a new modern lightweight, high performance belay device - look no further!

A beautifully simple design, there isn't much to go wrong - with obvious design origins in the old style plain tube belay device, the Mantis, weighing in at 45 grams in a sport where weight matters it floats easily above its competitors. 

Tapered and grooved rope slots provide fantastic grip and breaking friction, holding falls confidently across a wide range of rope diameters (8.5mm - 11mm on a single rope or 7.3mm -9.2mm for double or half ropes) while allowing smooth, secure and controlled paying out while belaying, lowering or abseiling.
