DMM

Large, lightweight auto-locking carabiner

A large, yet lightweight, HMS carabiner with a short gate to maximize gate opening. The deep and wide top basket can take three clove hitches (<9.5mm rope).
Kwiklock - Auto-locking gate requiring two separate actions to open. Kwiklock gates are suitable when auto-locking gates are a necessity, but rigging systems are relatively static and anchor points are easy to monitor.
