Freestanding metal room divider screens are prone to falling if they are located in a high traffic area and not anchored in place. You can secure one edge of your metal room divider screen to the wall using a bracket system and drywall screws.
Alternatively, you can construct several removable bases for the screen divider out of pine or oak (as these wood types are easy to work within even if you have limited carpentry knowledge). First, measure the length of the screen and divide by 12”. This will give you the number of bases you need to attach. Depending on how wide the panels are, you could also craft one base per panel.
Cut 12” lengths of wood that are about 2” thick. Mark the center of the wood piece and cut a 1½” groove the same width as the screen divider panel so that it fits snugly inside. You can paint or varnish the wooden bases to match the divider.
Set up the room divider accordion-style, and place one of the removable bases under each panel.
