The 20 x 24" Gallery 12 Wood Frame Kit from Archival Methods is made to display a photograph, print or painting in your home or office. The kit comes with an Acrylite OP3 acrylic glazing and a 1/8"-thick acid-free foam backing board. The kit also provides a strainer to keep the material stable inside the pre-assembled frame. Matted prints fit inside the frame as well. You can adjust the 3/16" rabbet according to the thickness of the mat by screwing it down to hold the matted print in place. A Phillips screwdriver is the only tool you will need to assemble and disassemble the frame. The frame is made from solid poplar and is painted black with a smooth satin finish.
