Mega HMS Twin Gate Carabiner

Although it looks like a non-clipper, Grivel's Mega K6G Carabiner has a unique Twin Gate locking device suitable for belays and anchors. Twin Gate prevents the Mega from accidentally unclipping mid-belay, and it adds a surprising strength rating for reliable durability. The Mega has a sleek, streamlined design that works for the bolt-end of quickdraws, and you can easily tie Munter hitches once you get to the anchor.
