Jumar Ascenders

These ascenders are where the term ‘jumaring’ comes from. The integral handles are great for longer ascents. The trigger, which keeps the cam in open position, also acts as a safety block to the cam so that it can’t completely be opened when it’s in clamp position. This is a great safety feature, particularly when down jugging. This does however, require two handed manipulation, or a lot of trained dexterity to completely unhitch the ascender, so it is not as easy to clear pro, knots, ledges, etc...
