Why This Window Box Stands Apart
True metal planter: Naturally resistant to rust and corrosion.
Hand-finished copper look: Electroplated, hand-rubbed rustic finish, and sealed for warmth and depth.
Structural integrity: Thick iron frame provides long-term stability.
Designed for healthy plants: Wide opening + drainage holes support root health.
Easy seasonal care: Brackets make removal simpler for planting, cleaning, and refreshes.
Materials & Care
Finish process: The metal planter is electroplated with a copper finish, hand-rubbed for rustic texture, then sealed with a clear protective coat. The frame and brackets are finished with a black powder coat.
Optional annual protection: Apply a clear spray sealant (inside and outside) once a year to help preserve the finish’s appearance—especially in harsher climates.
Avoid constant overflow: Water spilling over the sides may cause spotting depending on minerals, chlorine, or soil additives.
Not for fountains: These planters are not designed for continual water exposure.
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.
Recommended Plants for Window Boxes
Window boxes look best when planted with a “thriller + filler + spiller” approach—one or two focal plants, supporting texture, and trailing greenery for movement.

Ideas for decorating your window planters for curb appeal
Is this window box suitable for year-round outdoor use?
Yes. The metal planter and powder-coated frame are designed for outdoor conditions. Seasonal care and optional winter storage can help preserve the finish’s appearance.
Does it include mounting hardware?
Yes. Mounting brackets and standard wood hardware are included. If you’re installing on masonry, brick, or another surface, you may need alternative fasteners.
Will the rustic copper finish change over time?
The finish is sealed, but natural aging may occur based on exposure, watering habits, and climate—many customers love the character this creates.
Can I mount this to a metal railing?
The included brackets are not designed for metal railing installation. For railing-mounted setups, we recommend exploring HoldItMate® systems.
Is this style available in other lengths?
Yes—this window box is also available in 36-inch and 48-inch sizes for wider window spans and fuller planting designs.
