Twin Track Shelf Lock

thingiverse

I used these to secure wooden shelves to Rubbermaid (tm) Twin Track rails instead of screwing up through brackets. This allows the shelves to be adjusted along the rail (simply tilt up and remove) without having to unscrew them from the brackets. It also solved the problem of finding just the right length screws for each different bracket length (and that the Rubbermaid (tm) suggested sizes don't penetrate enough of the board to hold securely).Designed to be secured using a #6 x 1 inch wood screw but up to a #8 x 1 1/4 inch should work too though it wouldn't sit as flush in the hole.
