Mammut Wall Alpine Belay Device
Here's what other sites are saying:
A belay device for use in alpine terrain, based on the tube principle. As well as securing a lead climber, the very light Mammut Wall Alpine Belay also allows one or two second climbers to be independently belayed in an autolocking mode from the fixed point. The optimized geometry also allows comfortable belaying as well as reliable blocking in the event of a fall by the second climber, the blocking action can be released again using a webbing sling and the large eyelet on the device. The V-shaped grooves allow the controlled holding of lead falls, even at low levels of manual force. Suitable for twin, half and single ropes from 7.5 to 10.5 mm in diameter.
The Mammut Wall Alpine Belay Device proves its versatility when you take it up big walls and multipitches. By utilizing the larger eyelet and the anchors, you can set the belay device into an auto-locking mode for top-roping your second (and/or third) with ease, and the smaller eyelet helps you lower them without any hassle. Apart from that, this belay device does everything else you need on multipitches, including lowering, rappelling, and standard belaying. V-shaped grooves give you the friction you need to reliably catch and lower heavier climbers.
