The Petzl® Tibloc Ascender is hands down one of the best tools in the arsenal. A unidirectional progress capture device, the Tibloc can be used for ascending ropes, connecting to fixed lines, or improvising a mechanical advantage pulley system. The only limit is your imagination.
The Tibloc's elegantly simple design makes it compact, lightweight, and reliable - with no moving parts, it's unlikely to break. It has a trigger cam with teeth, allowing it to work on even dirty or icy ropes. A hole for a keeper cord prevents you from losing this essential item. When used with skill, the Tibloc is one of your best friends in any rescue or hauling situation.
