I used to install thermostatic shower. Nicely cast and machined, the copper pipe is a comfortable fit. Takes longer to heat for soldering, watch not to overheat copper pipe in the process
These are one of the best end feed backplate elbows I've used
Used for connecting shower fittings into wall. I wanted something with a deeper threaded section as I was using behind a stud wall. Couldn't find anything so used two of these with battens behind. I had to work out what depth to fit it to take into account the thickness of Hardie Backer board, adhesive and tiles.
