I have a handmade bathroom medicine cabinet (recessed & flush with wall, with adjustable melamine shelves inside). I am looking for some replacement shelf pins for the shelves, and hope you can help (no local store has what I'm looking for). The round peg on the pin must be 5mm in diameter but, the trick is, the pin fit into a recessed adjustable metal track, that has a 1/4" diameter. Therefore, the shelf pins must also have a 1/4 protrusion so they can be inserted vertically in the metal track, and then turned horizontally to "lock" them in the track.
Any suggestions where I might find these? Thanks so much for your help.
