plate upward and the bottom two flanges downward.
• If mounting into the PMK-12L, bend the flanges approximately
90 degrees.
• If mounting into the BB-12L, bend the flanges back as far as they
can go.
7. Use four standard drywall screws (length should not exceed drywall
thickness by more than ½ inch) to secure the mud ring plate to the rest
of the assembly. The screws pass through the clearance holes in the
PMK-12L (or BB-12L) and are secured in the extruded holes of the
fastener plates.
8. Verify that the mud ring plate is level.
NOTE: Do not over tighten screws. Doing so may over-dimple or rip the mud ring
plate.
9. Use a #2 Phillips screwdriver and tighten the drywall screws by hand
so that they slightly dimple into the holes in the mud ring plate.
