Ce Certified Climbing Double Stop Descender Self-Braking Self, Hand Control ?Self-braking Anti-panic System?:The stop wheel and stop shaft can make the user easily stop and hold in position, providing protection for users, especially beginners. When the handle is pressed to the end, the rope will automatically stop descending to avoid accidental losses caused by sudden descent. Put the rope into the stop wheel, and effectively increase the rope friction by lifting the rope, so that the user can descend and stop at a controllable speed. ?Easy to use?: By using the stop axis, it is convenient to lock the rope. The holes at the bottom can be installed with quickdraw to increase friction, and the spring lock of the side panel can install and remove the rope without removing the quickdraw. ?Specification?: CE 1019 Certified.
