The DMM Mantis combined with the DMM Belay Master makes a great belaying set

    The DMM Mantis is a lightweight belay device, incredibly light at just 45 grams, that is suitable for all round climbing with single, half, or twin ropes.
    Equally at home on the crag, as it is down the gym
    It is compatible with a wide range of rope diameters, from skinny half-ropes to the thicker single ropes used for bottom roping at climbing walls.
    Despite its low weight, the Mantis is a high performance belay device, giving confident control over ropes from 11mm down to a super skinny 7.3mm.
    Ideal for those looking for a single belay device for all their climbing activities.
    Colour :  Orange
    Weight : 45g
    Rope Diameter : half / twin : 7.3mm-9.2mm,  single : 8.5mm-11mm
    Conformance : EN15151-2 : 2013
    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.
    And for greater and confidence inspiring control over a wide variety of rope diameters when belaying, lowering and abseiling.
    Two friction modes for varying application, 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.
    The DMM Belay Master is a very safe belay carabiner with a nylon clip that ensures the gate is closed and prevents cross-loading.
    When closed, the clip keeps the carabiner in its strongest orientation, prevents devices and knots from moving onto the spine, eliminates possible cross loading due to rotation.
    This feature makes the Belay Master the perfect belay carabiner for those new to belaying.

    Belay carabiner for consistent rope control and compatibility with belay devices
    Belay carabiners give smooth and confident belaying with tube and assisted breaking belay devices.
    They have full section top bars for consistent rope control and reduced rope wear.
    Their shape resists flipping into sub-optimal orientations when belaying, acting to ensure the carabiner loads along its strongest axis.
    Offset D carabiner for optimal loading and ergonomics
    D-Shaped carabiners encourage loading in their strongest orientation by forcing loads toward the carabiner spine.
    An Offset D refines this basic design by extending the top bar, increasing internal volume.
    This improves handling and compatibility with thick ropes and slings.
    Nylon clip ensures carabiner loads correctly
    The Belay Master's nylon clip prevents accidental opening of the locking mechanism, and ensures the carabiner loads in its strongest orientation.
    This makes an ideal belay carabiner for new climbers.
    Full section top bar for consistent rope handling and increased longevity
    A rope running over a full section top bar has more consistent handling characteristics than one running over an I-Beam surface. 
    Ropes loading over full section bar also bend less than those loaded over I-Beam surfaces, increasing rope longevity.
    Keylock nose eliminates snagging
    This carabiner's nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch.
    This creates a clean internal profile that won't catch on gear, bolts or slings, giving easier clipping and removal from systems.
    I-Beam construction for optimum strength to weight ratio
    I-Beam construction techniques allow carabiners to be lighter without compromising strength.
    This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
