Perfect Anchor Locker

By Shane O'Donnell Ranked #353 - Carabiners, Quickdraws, and Belay Devices May 10, 2010

These 'biners are great. I have the majority of my lockers as the Positrons, with just a Vaporlock as a belay 'biner. They have a very smooth gate action, I have never had troubles with clipping. The gate screws easily and fast, and is never a problem for beat up or pumped hands to work. They are bomb proof strong, I use them to build top-rope anchors mostly, but also to secure a belay and I also keep one on my PAS permanently for cleaning. The size of the 'biner limits its uses a bit, just not really enough room for a doubled rope for the rappel. And if you belay on a tube, not the best I recommend the Vaporlock, but it's fine with a GriGri. I love to keylock nose, never snags on runners, and makes clipping to bolts easy. My partner has only 1 or 2 of these, and mostly uses a combo of the Quicksilver Screwgates, or a DMM keylock, and he tells me he prefers my Positrons.

As far as I can tell, the coloured ones I have, with the copper-brown anodized coating has 3 different coloured gates, yellow green, orange, and the same brown, just if anyone is interested.
