Helmets, pulleys, belay devices, lots of knick knacks a climber needs. A climbing belay device is one of the most used pieces of equipment in rock climbing. We stock a wide range of belay devices and other hardware from brands DMM, Petzl, Edelrid and Black Diamond. We have 'ATC' belay devices, tubular belay devices and assisted-braking belay devices, such as the Petzl GriGri. Need an ascender or a pulley? We have them too.
