Beefed up, super strong Grand Daddy of lockers

Having pitched the Big Boa as the ‘Big Daddy’ of lockers, DMM went one further with this beefed up, super strong biner. The 30kN Boa is the – yes, and you’ve guessed it – ‘Grandaddy’’ of lockers.

It has impressive gate closed strength and is robust enough to cope with the toughest of rigging scenarios. And yet, because it has an I-Beam construction, it is still impressively light.

Other Features:
Gate Opening: 23 mm

— Ultra strong, large clean nose HMS locking biner
— Ideal for rigging; can accommodate multiple knots
— Large gate opening
— Easy to handle in gloves
— Strong I-Beam construction to save weight (almost 25% reduction)
— Available with Screwgate, Quicklock and Locksafe locking systems
