#10 on this list
Voile Strap (15" & 20")
Voile
Not a carabiner, and the most useful fastener in this list anyway. A urethane rubber strap with an aluminum or nylon buckle that stretches, grips, and holds through cold, vibration and abuse. Ski carry, splinted tent poles, roof racks, firewood bundles, broken pack frames — one strap fixes them all.

#1 on this list
RockLock Screwgate Carabiner
Black Diamond
The default locker for anything that matters. A large, keylock-nose HMS shape with a hot-forged body, a smooth screwgate, and enough basket width to take a munter hitch, a belay device, and a glove-thick hand all at once. If you own one locking carabiner, own this one.

- Can be overkill for very small, light items
- Not as strong as a dedicated cam strap for heavy, static loads
RockLock Screwgate Carabiner
