The Grivel Sigma Twin Gate utilises a fresh take on carabiner locking mechanism technology. This patented Grivel system has been designed to improve carabiner safety, whilst making the biners quicker and easier to use than a classic screw gate*.
The Grivel Sigma Twingate is a classic offset carabiner to be used in place of a normal snap link or wherever you want to add extra security like on your cams, hexes or on your last quick draw before a crux.
