WB DW 400 Series Flush Drywall Access Door with Mud In Flange

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 access panel has a flange that can be mudded over to provide a concealed finish. The WB DW 400 drywall access door/panel comes with drywall bead that surrounds the entire door. This drywall access panel comes with drywall bead supplied by ClarkDietrich. The drywall bead can easily be taped or mudded over providing a stealth like appearance once installed in the wall or ceiling. This drywall access door/panel ships primed white but can be painted over to match the surrounding wall and ceiling; however, this drywall access panel 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 sizes are available upon request. For the same type of drywall access door/panel, but with a recessed door to accept gypsum, see our WB RDW 410 series access door / panel. The WB DW 400 series is proudly manufactured by The Williams Brothers Corporation of America. MADE IN VIRGINIA - USA.
