Weight: 4.33 ounces (123 grams) Milled and finished in Taiwan from Australian aluminium 7075-T6.

I have added order options for our friends in Canada. The CA version included First Class International postage, and hopefully runs through the system adding the $8.50 shipping charge to get it up to actual. Note: this only works if you do not order anything else on the same order… and if you do, then the shipping charge is messed up and… okay, shipping to Canada is always messed up. Email me.

EUROPE: Critrs are available at CanyonZone.com in The Netherlands.

AUSTRALIA: Critrs are available from Adventure Base in Katoomba.

NEW ZEALAND: available from Aspiring Safety

CARABINER CHOICE: Some older Black Diamond carabiners have a bit of a lump above the top of the gate. Newer ones do not. There are very few climbing carabiners now that do not work with device holes...  on the website I recommend the two carabiners I sell that fit that - BD Rocklock and the Cypher Iris.

I have also noticed that some people do not try very hard, or expect it to be entirely easy. It can help to lube the carabiner with a bit of spit, a bit of soap or a bit of oil (I use olive oil) to get it there.

It is important to use a round(ish) stock carabiner, 12mm, for rappel devices, as the rope in some configurations runs across the carabiner and can abrade it. Worst case scenario, damp rope + sand long rappel can cut 1/3 of the way through a carabiner in one rap, so it is a good idea to have plenty of material there.

Inspection/Retirement: Please inspect your Critr from time to time. Flip it over regularly to evenly wear both sides. Retirement is called for when 1/3 of the material is worn away at any crossing. If it develops sharp edges, these could be a problem when you rappel double-strand, so watch out for this.

"CRITR: A good choice. I own far too many different types of rappelling devices, but these days I really only use a CRITR, and have encouraged many folks to switch to it. I own an ATC, but I usually only carry it as a lightweight backup device for the group. I descended Englestead the day after the fatality that started this thread, and being the first down had no belay. Just before the freehanging section I added some friction and the whole operation went smoothly with no concerns whatsoever. Yes, I can add friction with an ATC, but the ease at which one can do that with a CRITR or Sqwurel can't be beat. Complexity is not desirable when rappelling, especially when the people doing the rappelling may not be hardcore canyoneers with thousands of rappels completed. On my first trip through Englestead several years back I had a friend, a bigger guy loaded with gear, lose control of the initial rappel and it was only my belay that slowed him down. He was a big climber-type using an ATC, who simply was confident and hadn't given much thought to needing extra friction, and by the time he realized that he definitely really needed it, he didn't have enough control to stop and rig a Z-rig or anything of the sort. I have seen a couple of situations made worse by an ATC, and have never seen anything that would have been solved by it. Love the CRITR, great device."
