The Boa is a large and very strong offset HMS carabiner with a massive gate opening. The offset shape gives the Boa a lot of extra strength without compromising it's core function as a HMS, this means that not only can it handle standard HMS duties well - belaying, italian hitches - but it provides a lot of extra capacity and safety when it comes to rigging. Large design also works well with the Munter Hitch. 99g
