D Line trunking ends

I bought some D Line 16mm x 8mm trunking for tidying up my Ring Door bell wiring inside my uPVC door frame. The trunking is cheap by length but the fitting are nearly as expensive as the length of trunking.. I only needed an end stop so put these two together here. they are handed depending which end of the trunking you want to put a stop end in.

The inside of the trunking is not symmetrical hence the cut off in the design.(see photo) They fit with a push in and do not need glue etc
