Installing Magnets / Contacts / QuickSwitches
Sites often do not want an installer to rivet magnets to doors as the rivets show through on the outside of the door. To prevent this issue, we recommend using PL Premium® polyurethane construction adhesive. PL Premium is made to hold for the life of the items being joined. To install the magnets:
1. On the latch side of the door, locate the position where the magnet will be placed. Be sure that the magnet is located within ½ inch of where the switch is to be installed and that it does not interfere with the door rolling up or swinging. See Installing the Door Switches, for locations by switch type.
2. Use isopropyl alcohol or acetone on a lint-free cloth to clean the magnet location of construction dust, grease, and other contaminants. Allow the spot to dry before proceeding.
3. Use a caulking gun to run a ¼ inch bead of PL Premium along the back of the magnet from one side to the other.
4. Press the magnet in place on the door, holding it tightly for 30 seconds. Use masking tape to hold the magnet in place until the adhesive is set. Remove the tape after 24 hours. The magnet may be repositioned for up to 20 minutes before the adhesive sets or will have to be reapplied.
