Achieve quiet geometric sophistication on wall and ceiling registers with the Pattern L Wood Vent Cover - a precision laser-cut 1/4" Baltic Birch hardwood grille featuring a uniform grid of open squares, creating one of the cleanest and most architecturally versatile patterns in the collection, suited to modern, contemporary, Arts and Crafts, and minimalist interiors.
Interior designers select Pattern L for its foundational geometric form that reads as both modern and timeless - integrating without conflict into nearly any design vocabulary. The open square grid maximizes free-air area while creating a visually ordered surface that works equally well as a supply register or large return air grille. Available in Maple (ideal for painted finishes), Oak, and Cherry veneers on a 1/4" laminated Baltic Birch core. In larger grille sizes the grid reads as bold and graphic; in smaller sizes it becomes a refined, almost invisible detail.
Delivered unfinished and factory-sanded, Pattern L accepts paint or stain to match surrounding walls, ceilings, or millwork. Over 50 sizes available; overall dimensions are 1-3/4" larger than the duct opening each way. Maple veneer is recommended for painted applications.
