Custom Matte Black Steel Slotted Plaster Wall Return Air Grille

Flat 1/8-inch architectural steel cold-air return grille finished in fine-texture matte black powder coat, sized to clear historic wood baseboards and plaster openings.

• 1/8" cold-rolled 1008 steel with baked architectural matte black coat
• Custom border overhang clears tall historic baseboard trim
• Includes black mounting screws spaced for plaster lath or wood framing

Pre-war and early twentieth-century houses often tuck wide cold-air returns directly above tall baseboard moldings or inside stud bays with odd rough openings like 7-3/8" x 23-1/2". Stamped HVAC grilles sit proud with rattled louvers and wide bevels that collide with baseboard caps.

We cut your exact return opening with customizable border overhang (down to 5/8" on tight baseboard edges) and tiered rounded-end vertical slots that allow quiet, low-static return airflow.
