Method of assembling a frame

Method of assembling a frame comprising:

• providing a first frame member comprising a first end and a second end, a second frame member comprising a first end and a second end, a third frame member comprising a first end and a second end, and a fourth frame member comprising a first end and a second end, each of the first, second, third, and fourth frame members comprising a mounting surface;
• arranging the first, second, third, and fourth frame members in a rectangular configuration to form the frame, whereby the second end of the first frame member abuts the first end of the second frame member, the second end of the second frame member abuts the first end of the third frame member, the second end of the third frame member abuts the first end of the fourth frame member, and the second end of the fourth frame member abuts the first end of the first frame member;
• positioning a first reinforcement bracket along a first corner of the frame so that mounting elements of the first reinforcement bracket adhere to the mounting surfaces of the first and fourth frame members;
• positioning a second reinforcement bracket along a second corner of the frame so that mounting elements of the second reinforcement bracket adhere to the mounting surfaces of the first and second frame members;
• positioning a third reinforcement bracket along a third corner of the frame so that mounting elements of the third reinforcement bracket adhere to the mounting surfaces of the second and third frame members;
• and
• positioning a fourth reinforcement bracket along a fourth corner of the frame so that mounting elements of the fourth reinforcement bracket adhere to the mounting surfaces of the third and fourth frame members;
• wherein prior to positioning the first, second, third, and fourth reinforcement brackets along the first, second, third, and fourth corners of the frame, applying an adhesive along at least one of:
• (1) the mounting surfaces of each of the first, second, third, and fourth frame members;
• or (2) the mounting elements of the first, second, third, and fourth reinforcement brackets;
• and
• wherein each of the first, second, third, and fourth reinforcement brackets comprises an aperture that overlies a channel in a rear surface of at least one of the first, second, third, and fourth frame members, wherein the aperture is configured to receive a fastener for hanging the frame from a support surface.
