The FREINO carabiner has a friction spur for adding or adjusting friction during the descent. It is easy to use and compatible with I&';D S, I&';D L, I&';D EVAC and RIG self-braking descenders. When rotated, it makes the descender loss-proof when transferred from the equipment loop to the ventral attachment point or anchor. The FREINO Z has the TRIACT-LOCK automatic locking system. Features: The spur helps increase friction for improved descent control with a heavy load (e.g. two-person rescue situation) Rope is easily inserted into the spur, without opening the carabiner TWIST-LOCK automatic locking sleeve, unlocked by a simple rotation Keylock system helps prevent the carabiner snagging during maneuvers Used, for example, with the I&';D and RIG self-braking descender
