Orange DMM Mantis Belay Device image 1

Key featuresexpand_more

Designed for use where direct belaying is not required – think climbing walls and general cragging – with either full or half ropes, the DMM Mantis is a fantastic all-rounder.

The carefully sculpted rope grooves offer a greater grip on ropes from 7.3mm to 11mm, the rope slots allow easy loading, and the rear of the device ensures adequate lift-off for snag-free paying out.

  • Two friction modes
  • 45g weight
  • Compatible with half ropes from 7.3mm to 9.2mm
  • Compatible with single ropes from 8.5mm to 11mm
