Fed up of shifting and cross loaded karabiners? Choose this unique screwgate instead.

The Black Diamond GridLock Screwgate is designed for belayers who are tired of shifting, cross loaded ‘biners. 

Made with an easy to useGridLock that isolates the belay loop behind the gate, the karabiner is kept in place, eliminating any danger of cross loading. 

Made with a rounded, rope bearing surface, the GridLock Screwgate helps give you the maximum strength and smooth rope feeding you want.

The GridLock screwgate has a hot-forged construction as well as an  I-beam spine which transitions into a rounded, large rope-bearing surface. 

Intuitive and easy-to-use this design has a low weight of only 76 g (2.7 oz), perfect for long days on the rock face.

Beautifully designed, 15 January 2013
By Kafoozalem (Plymouth)
I got this to replace a belay master which had a plastic clip to stop the carbiner from rotating. Unfortunately you can lose the clip. The gridlock doesn't have this problem and looks way cooler. It makes loading across the gate of a carabiner impossible and makes you a safer belayer as a result.

awesome crab!, 01 December 2011
By wolfie (manchester)
i bought this with the atc xp and they both work great together, the belay device stays in position and doesnt shift about like with a normal hms crab. with a little practice it clips to your belay loop easily, well recomended!

gridlock biner, 26 July 2011
By dazza (devon)
bought this to replace the fiddly (imo)BELAYMASTER due to slightly wider bottom of biner.fitted the belay loop on my harness easily which was what i wanted .It took a few goes to get used to working with it but now it is second nature and it is really good knowing you CANT cross gate your biner !! every climber should have one !!
