Boa HMS Locksafe 2017
Description
This is the ‘Big Daddy’ of lockers – the ultimate rigging biner and one which is super strong and super tough.
It is large enough to accommodate several knots and has a very wide gate opening – just what you need in a rigging situation. All of which makes it a great centre use biner, but the story doesn’t end there.
Despite its name, the Big Boa is surprisingly light; by giving it an I-Beam construction we’ve reduced the overall weight by almost 25%. Add in the fact that it is easy to handle in gloves and the appeal to winter climbers is obvious.

-Ideal for rigging; can accommodate multiple knots
-Large gate opening
-Easy to handle in gloves

This is a great belay device locking carabiner or all-around locker. We found it was one of the easier ones to operate with gloves, which makes it ideal for winter use. For belaying we liked the twist-lock gate version the best. The screw-lock gate is also effective, but we feel it is better suited for an anchor or backup biner.
