Round edge 60 is a hold ideal for vertical walls to a slight overhang. The grip is 60 mm deep, with a huge edge radius.
The big edge radius makes the hold quite hard to grab in a big overhang. It feels more like a sloper / pinch in overhang bigger than 30°.
We are using solid wood to make our holds, there are 2 holes drilled for 5mm screws and a steel washer in each hole so the screws don't damage them. The screws come in perfects sizes with the holds, so you don't need to buy them extra ;)
