User Review: Petzl Tibloc
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.
