Quick Overview

If you need a large ally screwgate carabiner then you should be looking at the Boa.

The DMM Boa is a large alloy screwgate carabiner. It has been a mainstay of our range at Bogong for many years. It is now improved with an I beam hot forged construction and a taperlock nose.

The unique curved back shape gives heaps of internal space making it ideal for rigging and setting up belays and top ropes. All this space and the Boa still only weighs 83 grams.  Like all DMM carabiners the finish on the Boa is superb and it is 100% made in Wales. Like all HMS carabiners it works well with a Munter or Italian hitch.
