Headboard Slotted Bolt Adapter Plate
A ribbed 160 x 60 mm adapter plate for a headboard whose bolt holes don't line up with the bed frame bracket. It has four 8.6 mm slots, 50 mm long, in two rows 32 mm apart, and takes 5/16 in or M8 headboard bolts set anywhere from 30 to 130 mm apart. The flat lands around the slots fit a 22 mm washer, and the plate's 9 mm stiffening ribs face away from the headboard.
Universal Smoke Detector Box Adapter Plate
A 130 mm ceiling adapter ring, 6 mm thick, for fitting a new smoke or CO detector to an old electrical box. The counterbored box slots sit on a diameter and run from 66 to 94 mm hole spacing, which covers 3 in round, single-gang (83 mm) and 4 in octagon (89 mm) boxes. Four radial M4 slots for the detector have a captive-nut track underneath and reach 64–116 mm screw spacing, and a 50 mm hole in the middle lets the wiring through.
