ISC "Gator" - Good biner but it damaged my rope sn, Thursday, 01 May 2008

Just know that, because of the "knife edge" shape these biners have, one did find its way under the safety plate of my rope snap (only on one side) and pried and bent it. Completely away from the little metal protrusion that's supposed to keep it snapped! I don't know if the larger sizes have a thicker edge, but my Gator and my steel rope snap got into a tussle.

Of course it was during a difficult job where I was double crotching and reaching and twisting far out on a limb, and I wasn't paying attention to the way the biner and rope snap were interacting. The rope snap scratched the Gator up a bit but no real harm done.


So I though that was worth mentioning. I use a rope snap instead of 2 biners when I do a split tail climb because sometimes 2 biners can get "inside each other", but I never had a probem with a snap entangling on a biner. Until now. So I switched this ISC biner out and now I'm using something much rounder and fatter that cannot get under the rope snap edge.

But it's still a cool biner cause it's compact, strong, colorful, and has a very positive action and feel.

This carabiner is the middle size in a set of three from ISC. The largest is the Mongoose, the smallest is the Gator. They all share the same shape and proportions.

ISC is known for having very strong return springs on their sleeves. This is a great feature that is more likely to overcome any debris that might be in the sleeve. The knurling on the sleeve is just coarse enough to allow the climber to grip but not so coarse that the sleeve is likely to open from touching a rope or other moving piece.

Like all double acting gates these carabiners take a bit of trial and error to find the best way to handle the gate.

The unique shape of the carabiner forces the connection point on the small end and the attachments at the large end to slide back towards the spine. Keeping the load away from the gate side of the carabiner makes for a safer carabiner.
