These magnets are simple to install and easy to hide behind your sign. All you have to do is screw the magnets into your wall at your desired locations. Place the metal sign on top to cover up any part of the magnet. With no hanging hardware actually showing, your sign will look its best!
The magnets will not work on clocks because the mechanism used to operate the clock hands is thicker than the magnets. 30" pieces will need 2 sets.
CAUTION: These are high-powered magnets. Once these magnets are separated, please do not allow them to come in contact with one another or any metal surfaces as the impact will cause damage to the magnets or the magnetic surface.
The magnets measure 0.75" in diameter. They are 0.25" thick. The screws measure 1.5" long. You will receive 4 round magnets and 4 screws. No other materials necessary.
