| Summary: | external spring, semi-locking carabiner |
| Description & Commentary: | A very interesting locking mechanism - a wiregate pushes against an un-sprung solid gate. The solid gate cannot be opened without first opening the wiregate. I do find it disconcerting that the solid gate is unsprung and will flop around once the wiregate has been opened. Perhaps this is best understood as a wiregate guarded from accidental opening by the solid gate. Suitable for winter climbing, there is little to freeze solid with snow and ice, and the locking mechanism can be opened with gloves. The bent spine and flat runner end are also rare to find in such a small carabiner. |
