Hot forged light alloy screw gate HMS with keylock gate and special spring fastener that stops the krab turning round in circles and so removes the danger of cross loading.
Suitable for use with a tape already slotted in place behind the spring as a cow's tail when sport climbing, or for use with a belay plate when the spring is fastened round the belay loop on your harness.
Hard anodised for extra wear on gritty ropes.
