Materials & Care

Materials: The Williamsburg window box includes a stainless steel planting box with an antique copper finish and thick iron mounting brackets with a black powder-coated protective finish.

Antique copper finish process: The planter is electroplated with a copper finish, then hand-rubbed to create an antique look, and sealed with a high-grade clear-coat protective sealer.

Optional annual protection: You may apply a clear spray sealant once per year (inside and outside) for added protection—some customers also apply it before first use.
  • 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: Brackets are not designed for metal railings. For railing mounting, explore HoldItMate® systems.
