ATC guidelines recognize that safe descending and belaying come from using a device that provides controlled rope friction, and they approve a range of devices for this purpose rather than constraining you to one type. Tubers (tubular friction devices) and stitch plates give straightforward friction control; JRDs offer a different braking action with their geometry; GriGris provide assisted braking to help manage the rope under load; and certain figure-eight devices (specified models) are also permitted when used correctly. When you’re trained and rope compatibility is confirmed, using any of these devices with proper technique gives reliable control, arrest capability, and smooth descent. The other options omit some of these approved devices, which is why the full set listed in the guideline is the best answer.
