Finger plate for campus training. This is a plastic hold made with a 3D printer. The top surface is flat, and the bottom surface is slightly incut, allowing for 2-way use by changing the mounting direction. Friction can be felt to some extent even without chalk. Sufficient friction can be felt by using chalk or PD9 in combination. ⚠️ Important Notes for Use Compared to general resin-molded or urethane holds, the strength is inferior. The creator himself uses it daily, and no major problems have occurred to date. Over-tightening the screws can cause damage. Please be careful not to overtighten when installing. PD9 is for size comparison and is not included. Please use at your own risk.
