Black Diamond ATC Guide Belay Device

Black Diamond ATC - Guide One device to do it all, the ATC-Guide offers maximum versatility. It has a smooth regular friction side and for twice the friction, a grooved high friction side. When you’re belaying from above, the guide mode lets you bring up one or two seconding climbers. For lowering, it has a small secondary hole that you can girth hitch for more leverage to release the device.
