Colouring trash picker

Step 4 Drill a hole above the superior clamps

On a distance of 3 inch (75 mm) above the place where the clamps are mounted, you need an axle as a rotation point for the metal strip that is going to push the head of the graffiti can. On this distance, drill a hole where the bolt M4 will fit through. Make sure there is little margin. Attach the bolt, washer and the spacer on the pole. The spacer must be at the left side of the pole.
