Grivel Sigma Twin Gate


The Grivel Sigma Twin Gate is a unique double gated offset climbing carabiner, offering extra security in place of a normal snap link. 

Utilising a fresh take on locking mechanism technology, this patented Twin Gate Grivel system has been designed to improve carabiner safety whilst making the biners quicker and easier to use than the classic screw gate they've been designed to replace*.

*Although this does take some practise.

Use the Sigma Twin Gate in place of a normal snap link or wherever you want to add extra security, like on your cams, hexes or on your last quickdraw before a crux.
