I created these endcaps to enclose diffuser track that was cut to custom lengths that didn't perfectly match the cut lengths of the LED strips. These also afford more flexibility in dealing with the wiring side of the strip since the stock endcap doesn't account for pre-wired plugs.

Caps are 40mm in length and fit very tightly to the aluminum channel while still giving a small surface to use VHB tape or other mounting adhesive.

Dimensions:

Inside opening 18mm x 9mm

Outside 24mm x 12mm

Length 40mm
