Easy on/off switchable magnetic cabinet latches designed with rare earth magnetic device to tenaciously attach themselves to the striker plate. In the off position, the polarity of stacked magnets oppose each other eliminating magnetism. Rotate the switch to the on position, and the magnets align and create magnetic force. Add your own knobs, pulls or handles - fits any std 8-32 or M4 knob (not included). With holding power of 10lbs, doors close securely everytime, and stay closed. Keeps even the most stressed doors closed on mobile homes, boats and trailers and then quickly releases with just a turn of the handle. 2 Striker plates included.
