The Tibloc is light and compact ascending tool that should always be in your pack if you’re carrying rope. It’s perfect for self-rescue in a crevasse and ascending a rappel that didn’t quite make it to the dance floor. Rather than carrying around a full-size ascender, just hook a carabiner through the hole and the angled directional teeth go to work. The body is made of corrosion resistant stainless steel to improve longevity while the self-clearing capabilities of the angled teeth increase bite when conditions are muddy, icy, or wet. The Tibloc is faster than a prusik, lighter than an ascender, and small enough that there’s no reason not to have it with you just in case.
39g means even if you’re a weight-weenie like some (okay most) of us, you can justify carrying it.
Stainless-steel construction resists corrosion so it’s ready to go when you need it most.
Fits 8mm to 11mm ropes with a locking carabiner, 10mm-12mm with an oval carabiner.
CE EN 567 and UIAA certifications.
Update 2018: The Tibloc got a bit of a makeover. Aside from the orange color, the new version has has an automatic system that presses the carabiner against the rope to start the braking action on the rope. This is significant with use of smaller diameter ski mountaineering cord, making it easier to use, quicker to "bite" on the rope, and more efficient.
Purists might scoffingly assert that any mechanical advantage raising/hauling system should be built exclusively from biners and prusik cord. But the Petzl Tibloc is so trivially small and so trivially light yet so incredibly useful for building such systems (especially for crevasse rescue) that it rates Five Stars for sure.
The picture shows one caution and one tip: - As also illustrated in the user manual, be sure to clip through the body of the Tibloc and hence also through the rope, not just through the hanger extension. - If you tie a little loop with some thin accessory cord, then you can attach a stuff sack weighted with snow so as to drop(/lower/slide) the loop of a 6:1 Canadian Droop Loop down along the travel rope to a victim in a crevasse fall when you're unable to toss the loop down to the victim to clip in, thereby pulling up the victim sort of indirectly by hauling up the original travel rope, i.e., rather than hauling up on the victim's harness. (This will lose the advantage of hauling out the victim on a strand that hasn't already been sawing into the edge of the crevasse, but it's still a potentially helpful trick.)
Speaking of cautions, for use instead as an ascender, remember that many rope owners (perhaps yourself!) will freak out over the prospect of damaging the sheath by ascending on a Tibloc with all its menacing-looking teeth.
