Under-Sink Spray Bottle Hanger Rail
A 180 mm screw-on rail for the inside wall of an under-sink cabinet. It hangs three trigger spray bottles by the neck, so they stop tipping over in the cabinet base. Each 60 mm-deep shelf has a tapered slot that narrows from 34 mm to 22 mm, so necks of different sizes wedge in and the trigger head sits on top. Slots are on 62 mm centres. Four 4.5 mm holes take #8 (4.2 mm) wood screws, and four 45° gussets carry the load.
