Mind the Carabiner Gate There Ice Climber

Grivel-360-Ice-Screw Crank Opening Gate of Carabiner
Oops! Check out what can happen if the crank handle on our Grivel 360 ice screw whips around into the gate of the carabiner we’ve got clipped into our ice screw. Kinda scary, eh? Yeah, I thought so too. The screw crank has cleverly opened the carabiner gate! Yikes! Don’t want to be taking a whipper on that thing, that’s for sure.

Here’s a close up for greater horrorshow.

My buddy Terry Brenneman took these photos while cleaning an ice climbing lead in the lower Ouray Ice Park. Before you freak out, assuming you climb with Grivel 360 ice screws, Terry suggests this might have been an early design flaw that’s since been remedied. “All my other Grivel 360s have a crank handle pivot which binds throughout its range and doesn’t flop around (see photo below),” he noted.

As you can see, the current 360 (on the left) has this triangular bend in the crank handle wire to keep it from flopping about. The Grivel 360 Jive-Ass Edition® (on the right) doesn’t have it. It’s got some other sort of wire bend at the end.

Terry explains, “I suspect the rogue screw is an obsolete desipgn which made it onto the retail floor (purchased around 2007 but it was a good deal!). Don’t need this false protection jive-assery on my rack.” And how!

Something to keep an eye out for. Has anyone had something like this happen?

Climb safe out there kids. Ice climbing is hazardous!
