The Hale Magnet and Strike Set
The Magnet and Strike Set provides everything you need to add a Hale magnet with carrier in the frame and one Hale strike opposite the new magnet on the flap. The fuzzy weather strip is cut with scissors to make room for the magnet which just presses into the frame. The strike is applied with pliers.
Additional Hale magnets are handy in very windy situations where the flap is blowing open and also to help keep the flap in alignment with the frame.
If you choose, you can purchase a Hale magnet by itself or a Hale strike by itself on this page.
