Door Stabilizer
is a clever magnetic mechanism that stabilizes any top-hanging room dividing door. This device adds a second point of contact to the bottom of the door on the closing side.
How it works is a retractable cylinder Pin is fitted in the floor at the closing side of the door. A magnetic casing that receives this pin is fitted to the underside of the door on the closing side again. So once the door slides closed and the magnetic casing passes over the steel floor pin, it pops up and locks in position, preventing any wobble of the door once closed.
