Loading... Please wait...With its revolutionary, patent-pending design made possible by our in-house hot forge, the Black Diamond GridLock Screwgate eliminates the dangers of cross loading. Designed specifically for belaying, the intuitive, easy-to-use GridLock isolates the belay loop behind its uniquely shaped gate, thereby keeping the carabiner in its proper orientation. The GridLock's I-beam spine transitions into a large, rounded rope-bearing surface for maximum strength and smooth rope feeding. Simply put, you'll never have to deal with a shifting, cross-loaded belay carabiner again.
Weight : 76 g (2.7 oz)
Closed Gate Strength : 22 kN (4.946 lb/f)
Open Gate Strength : 8 kN (1,798 lb/f)
Minor Axis Strength : 7 kN (1,574 lb/f)
Gate Opening: 21 mm (.83 in)

I like belay biners that prevent crossloading. So after the plastic dohickey on my DMM Belaymaster popped off and went into the ocean somewhere beneath Ko Yawaban in Thailand I was looking for another solution.
I never really liked the way the DMM was dickey to rack with that silly plastic arm. While it worked well when in use, it always got caught on things when racked. The Gridlock doesn't suffer this issue.
You clip it into your belay loop, spin, pull and CLICK, it's locked in place. I use it with my SUM device and it's been smooth sailing thus far.
