US Patent 7331369 Sliding door magnetic latch

A magnet holder constructed of a resilient material as a plural-sided box has an open side. A bar magnet within the magnet holder extends outwardly from the open side. A second side of the box has an arcuate convex shape extending outwardly. A hollow door frame strut provides a first interior surface abutting a third side of the box. The magnet abuts a second interior surface of the strut with the second side of the box abutting a third interior surface such that the arcuate shape is flattened, springfully wedging the box between the first and second interior surfaces of the strut and securing the magnet holder in place within the strut.
