DMM Boa 30kN HMS Screwgate

6 reviews   |  

The DMM Boa 30kN HMS Screwgate is a super strong offset HMS carabiner, designed for the toughest and most demanding rigging scenarios.

In spite of its incredible strength and durability, thanks to the now well familiar I-Beam construction, this BIG Boa, at 95g, is surprisingly light. With a massive gate opening (24mm), 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.

What you expect

Great DMM quality as usual, surprisingly light for the size and feels absolutely bomb-proof.

Big boa

It's big enough for three clove hitches and stronger than your regular screw gate so you can lord it over those you climb with and their inferior crabs. Smooth screw and a satisfying kerchunk with the gate.

I needs to balance out

I needs to balance out the strength across my HMS biners for rope anchors and room was getting tight at times when multiple ropes, and other equipment were running through my others. I bought 5 30Kn Boas to give me a balanced high level of strength across them and the room in the biners is excellent. Add to that the impressive aesthetics of DMM equipment and I'm very content, an excellent product.
