The Best Drywall Access Panel with Mud In Flange in the Industry. A quality flush WB DW 400 access
door with a tape-in drywall bead flange, eliminates visual distraction created by projecting, surface-mounted units. The WB DW 400

comes primed coated white. This flush mud in access panel is perfect for any application where a flush mud in flange drywall access
panel is required. This door is available in all the popular sizes such as 8x8, 12x12, 18x18, 24x24, and many more; however, custom
