A flared window box with an antique copper finish—paired with a decorative scrolled metal frame for a traditional, architectural look. This 36-inch length is a favorite for classic curb appeal: wide enough for fuller plantings, yet still balanced on most standard window spans.
Handcrafted from stainless steel and heavy-duty iron, it’s designed for outdoor use and easy seasonal refreshes—from spring blooms to winter greens.

Materials & Care
Materials: This window box includes a stainless steel planting box paired with a welded metal scrolled frame/bracket system finished in black powder coat.
Antique copper finish process: The planter is electroplated with a copper finish, hand-rubbed for an antique look, and sealed with a high-grade clear-coat protective sealer.
Optional annual protection: For extra protection, some customers apply a clear spray sealant once per year (inside and outside).
Avoid constant overflow: Minerals/chlorine/soil additives can contribute to spotting if water runs down the exterior.
Not designed as a fountain: Continuous water exposure is not recommended.
Winter storage: Optional. Clean with mild soap + water, dry thoroughly, then store if preferred.
Mounting note: Not designed for metal railings. For railing mounting, explore HoldItMate® systems.
