Figure 2-8 — Attaching a mud ring to a wall

If you are using a wall box, insert the wall box into the opening, and attach it to the wall stud/furniture with nails or screws, leaving the front edge flush with the outer wall or furniture surface (figure 2-9).

If attaching the wall box to wood, use four #8 or #10 screws or 10-penny nails. A minimum of 1/2 inch (1.3 cm) of screw threads must penetrate the wood.

If attaching the wall box to metal studs or furniture, use four #8 or #10 self-tapping sheet metal screws or machine bolts with matching nuts.
