DMM PIVOT Belay Device This device is characterized by a pivot mechanism that is effective in guide mode, as shown in photos 3 and 4. It is said to release with significantly less force compared to other devices in guide mode (see photo 5), and the release carabiner hole is also large. Compatible with rope diameters of single 8.7-11mm / half and twin 7.3-9.2mm. For those who don't often use guide mode, it's probably not necessary to purchase this item considering the price, etc. For those who do multi-pitch climbing, why not try it for second belaying/lowering? Although unused, this is a used item that has been handled by someone. Please use it at your own risk. Thank you for viewing.
