The DMM Mantis is an incredibly lightweight belay device for use with either single or half climbing ropes, perfect for all types of climbing at the wall/crag. Now improved and using the same high performance internal geometry as the Pivot, the DMM Mantis has carefully sculpted rope grooves that offer a greater grip on all climbing ropes from 7.3mm to 11m. The rope slots allow easy loading and the rear of the device ensures adequate lift-off for snag-free paying out. If you are after a lightweight, versatile, single belay device for all types of climbing needs then the DMM Mantis fits the bill perfectly.
