Mainstays 12 x 18 Black Plastic Wall Frame

Sized for 12 x 18 prints

This Mainstays wall frame holds a single 12 x 18 poster, photograph or artwork behind a clean black plastic border. It is intended for anyone who wants an affordable way to display one piece of art on an indoor wall without custom framing. The simple rectangular profile suits bedrooms, living rooms, home offices or any interior space where a personal touch is wanted. Buyers needing multiple openings or a different aspect ratio should look elsewhere.

19.62 x 13.37 x 3.25 inch outer dimensions

The assembled frame measures 19.62 inches high, 13.37 inches wide and 3.25 inches deep, so the wall cavity and surrounding clearance must accommodate that exact footprint. Verify the available space before ordering because the moulding cannot be trimmed or resized after purchase. The single opening is cut precisely for a 12 x 18 print, leaving no overlap for larger or smaller media. If the aperture size does not match your artwork, this frame will not work.

Indoor wall-mounted use

The frame is designed for permanent indoor wall mounting and is not rated for outdoor exposure, high humidity or freestanding display. Under normal household conditions the black plastic construction resists warping and colour shift over time. It ships ready to hang with the hardware needed for a single flush installation. Long-term stability depends on the wall surface and fixings used rather than on the frame itself.
