Price Paid: under $25
I first saw this device in a climbing mag. As a rescue tech., I/we are always looking to try out new ideas, especially when they are this inexpensive and LIGHT!
The Tibloc can be used as an emergency ascender on single rope up to 11mm (I've used it on 12mm with no probs.) and also as a makeshift locking pulley for hauling systems like the Z-rig. Works best with an oval or HMS carabiner with a round body.
Plus side: Super simple, can't be removed from rope unless the attaching biner is removed also, inexpensive, small enough to carry unnoticed on any rack. Great self rescue back up ICO emergency.
Minus: Not rated for double loads found in rescue, teeth MAY wear rope (they haven't for me yet), small size make it easy to drop, especially if wearing gloves - tether it with a length of accessory cord. Not a stand alone piece - requires a carabiner to complete the system.
I keep one (or two) of these with my rescue gear, tree climbing kit, and my rock bag.
I rated this product high because I believe it's one of those "Don't leave home without it" kind of emergency items.

This ultralight, multi-purpose rope grab is an ideal back-up for standard ascenders or for those who wish to travel as light as possible. Much lighter and more compact than standard ascenders, plus faster to set up than prusik knots and works well in pulley systems. Tibloc should be used only with carabiners made of uniform oval or round stock in order to prevent damage to the rope. Caution: hot-forged carabiners with T-shaped stock, such as the Petzl Spirit, should NOT be used. The Tibloc is an amazing little tool when used properly, but can easily be misused; it is essential to read the instructions to prevent rope damage!
The Petzl Tibloc Ultralight Ascender serves so many purposes that it has a place on nearly any long rock climb, aid climb, or alpine climb. Pair this simple 1.4-ounce ascender with an oval-stock carabiner to create a self-locking pulley for bag hauling, crevasse rescue, or aiding a partner up a pitch. It can also be used as an ascender if you need to climb a rope to free a rappel or just can't follow a burly pitch. The Petzl Tibloc Ultralight Ascender also serves a multitude of uses in self-rescue situations.
