Top Gear #27 - Edelrid Pure Slider Carabiner

They were originally designed so they could rotate in a bolt hanger and they do that easily, they can be used with a clip stick with no problem, they are ideal on a first quickdraw where you want to be sure the carabiner gate can’t be compromised as you climb past and, if you don’t want to carry a screwgate for every situation that would normally warrant one,  they offer a good in between choice and save around 10 grams on the weight of a screwgate (depending on screwgate model).
