The DMM Boa is a large and clean nose HMS locking carabiner. Ideal for climbing, the Boa can easily accommodate multiple knots. It has a large triple locking gate and has a strong I-Beam aluminum construction. Because of this, the Boa has a massive 30KN breaking load.
The Boa makes a great belay and rappel locking carabiner. It has a smooth gate, holds lots of ropes, and has good gate clearance. Because it is light for its size, it is a hard option to beat for an arborist or tree climber.
The DMM Boa is also available with an ANSI compliant lock safe gate which conforms to EN362:2004/B, CAN/CSA Z259.12 (2011) and ANSI Z359.12 (2009).
