This set of pinches are narrow. In the 1-1/2" range, which is the thickness of a 2 x 4. You'll love these because they have a minimal footprint yet offer an excellent training hold. When considering the wall's angle you want them on, expect V1 on vertical and V4 on a 45-degree wall. Pinches like these are an excellent choice for beginners on vertical as the incut divots give the climber a positive purchase. On vertical, you can also cheat the hold with a finger on top. For steep walls, the spinner screw is at the top of the hold. There is a taper where the spinner screw is, so they offer a steep smear foothold. They will be challenging to stand on in steep terrain.
