You will need a T-30 size Star Driver, and a drill bit to make a pilot hole in your wall. Let us know if your situation requires different length screws. If you choose to mount using the T-30 deck screw option, we will supply 3-inch deck screws (4-inches long for 2 inch thick signs) with a Star-Drive head, and we will pre-drill the holes in your plaque. The keyholes and screws will hold the sign while the glue sets, making a permanent installation. After a trial fit, put some adhesive in the keyhole bracket holes, or stronger yet, put adhesive on the wall within the borders of the sign. Be certain that whatever you use is compatible with your surface. Using adhesive is highly recommended for exterior or exposed locations use of a polyurethane construction adhesive is likely to be the most suitable. This is fine for interior, but even moderate winds could lift your plaque and send it crashing. If they are left loose, the sign can easily be lifted off the screws. For the best holding power, the screw heads should be adjusted to have some contact with the keyhole unit. Drive the screws into the wall but leave them out a little so they can engage the keyhole mounting brackets. Use a level to make sure that you have the holes even. Measure twice or three times make sure you are right before you drill. Measure the distance center to center of the keyholes installed on the back of the sign. For interior use, picture hanger hooks, or even nails, may be sufficient. The keyhole method will work both interior and exterior and requires a flat surface. We include suitable screws that are appropriate to most situations. Keyhole mounting brackets are pre-installed on all wall-mounted signs unless otherwise specified. Can be a good choice for smoother brick and stone surfaces as well. Consider for interior and exterior walls, doors, and stucco. Keyholes are generally best for mounting your sign or plaque on relatively flat surfaces.
