DMM Boa Screwgate HMS: Coloured 3-Pack

2 reviews   |  

Sorry, this product is out of stock. We can notify you when this product is available:

The DMM Boa Screwgate HMS 3-Pack is a set of three large and strong HMS Boa's in green, red, and blue.

Great for rigging and belay situations, this very large and very strong offset HMS carabiner with a massive gate opening (24mm), can accommodate several knots. The offset shape gives the Boa a lot of extra strength without compromising it's core function as a HMS, allowing it to not only handle standard HMS duties well - belaying Italian hitches - but providing a lot of extra capacity and safety when it comes to rigging.

The Boa Screwgate has been one of the most popular DMM carabiners, handling all tasks and performing at high levels, and now it has just got even better!

    Great Carabiners

    2nd to none large carabiner. Great for use with a reversible Belay allowing the Italian Hitch to invert with ease. Also great product for use with Belay Gloves on an adventure park scenario, allows plenty of room for rope to pass even with gloves on. Only minor point, the Carabiners has been updated in styling, so not exactly like the picture shown, however, I knew about this so wasn't an issue, could be an issue is you were wanting to do a straight swap and have a little OCD.
