The Grivel Mega HMS Twin Gate is a double gated carabiner for your climbing safety. The hinges are opposite from each other, which won't allow either straight gate to open unless the other does. This set up won't allow the rope to unclip without help, so each portion of your climb is that much safer. Pear-shaped not just for looks, but for an easy fit in one hand and plenty of space for the rope on the inside.
FEATURES of the Grivel Mega HMS Twin Gate
Twin gate allows for quick and simple clipping, and once both gates are closed, the 'biner offers the same security as a screwlock carabiner
Large-framed, pear-shaped body makes it ideal as a belay 'biner or as an anchor 'biner
Very large carabiner for belaying with Munter hitch and for rappelling, with single or double ropes

Twin gates rule, but this one's not the bestI've immediately fallen in love with Grivel's twin gate locking carabiners. I was surprised how natural they feel - after just a few minutes I feel like I've been using them for years. This one's no exception in that regard, and the familiar pear shape is welcome. Even when it rotates, the rope runs smoothly across the large twin gates. Unfortunately, it suffers from two problems. 1) The diameter is a little too big through the gates to work well with a GriGri 2. With some twisting you can get it through, but it's hard to move around and generally a pain to use, requiring some modification to the GriGri for a proper fit. 2) The gate opening is tiny. Really tiny - and much smaller than is forgivable on a biner this size. Even the much smaller Plume twin gate (my fave) has a larger opening. It doesn't make any sense, and makes this a difficult carabiner to use regularly. I suggest either the Lambda or the Clepsidra as a belay locker - they each fit a GriGri 2 better, and both have far wider gate openings.
