BlueWater Ropes Ranger Belay Device
Mountain Gear says:
The Ranger Belay Device from BlueWater is constructed from 7075 Aircraft Grade Aluminum for lightweight safety you can count on. Works with rope diameters 7.7-11mm. The ribbed channel gives you complete control over the rope by adding extra friction for increased breaking power. Multiple attachment points allow you to easily belay one or two seconding climbers.
