Bolt on System Slopers #4
The below description is very similar to Sloper #3 however, this one, #4 is a more slopier/difficult to hold version. There's lots of room for your hand on this hold. The indent at the back of the hold gives you full on open hand sloper training or if you have a little Brit in you, you might try to open hand crimp it like gritstone.
Sold as a set of 2 holds.
