Mantis

The DMM Mantis is a featherweight belay device that is suitable for all round climbing with single, half or twin ropes from 7.3mm to 11mm.

It has been optimised for 8mm to 10.5mm ropes.

Hot forging the aluminium alloy has allowed DMM to create a high performance belay device that weighs just 45g, yet is robust enough for heavy use. The internal geometry is precisely machined with a subtle taper to give an optimum balance of smooth handling and braking friction. Extra friction is added by the deep V-shaped rope slots. Grooved for additional grip, they do a great job when you need to hold a fall, or when feeding out rope slowly and in control i.e. lowering a climber or abseiling.

The rope slot allows easy loading and the the shape of the rear of the Mantis helps encourage "lift off" (lifting the belay device away from the carabiner) - this means it doesn't jam against the belay carabiner - so paying out rope to the lead climber is quick and smooth, not jerky or grabby.

High performance internal geometry gives greater rope control.

Hot forging and CNC technology is used to shape the internal structure of the device to give greater control over a wide range of ropes. This is especially evident when using modern, small diameter ropes.

Two friction modes for varying applications.

In its standard orientation, this device gives confident control over a wide variety of rope diameters. It can also be flipped 180° for smooth abseiling on thick or low stretch ropes.

A few grams here or there may not sound like much in the scheme of things, but it soon adds up, and anyone who is making an effort to reduce the weight of their hardware is going to appreciate the lengths DMM have gone to here. UKC
