Edelrid Zap-O-Mat

With its adjustable tension spring the Zap-O-Mat is the worlds first adjustable belay device. The ingenious idea of having a loaded spring in the handle means the Zap-O-Mat is ideal for every sport climbing situation and for every belayer regardless of weight or rope thickness. Push the green “spring load” button in and the rope can be paid out easily for on sight or red point attempts. Release the spring by pushing the button on the bottom side of the handle and the central bolt moves easily and the Zap-O-Mat blocks quickly. Usable for single ropes from 8.9mm and 10.5 mm and weighing only 135 grams, the Zap-O-Mat is a hybrid tuber unit and not a semi automatic belay device.
