The STUBAI BC PRO is a lightweight and compact belay and descending device. The device impresses with ribbed V-shaped brake notches. Made from forged aluminium, the Tuber can be used in two positions: either high stopping force on the ribbed side or less brake friction on the opposite, smooth side. The rope output works best in both positions. Perfect for dynamic securing and rappelling. The BC PRO is gentle on ropes and prevents annoying tangling and thus ensures a long service life of climbing ropes.
