Review on 💦 Transform Your Shower Experience with the HOMEDEC Brass Square Shower Body Spray Jets Head in Matte Black (6pcs) by James Beird

1. It's true the patch can't go past (or over) the collar. So if your measurements are wrong, you will see threads. The lining of the liner is stainless steel, so drilling with a unibit or similar won't work. Solution. I used a hole punch (usually used in electrical work) to enlarge the hole so the body of the light fitting could fit through, covering the threads.2. The included brass nipple is removable. The mount has a rubber washer/shield and you can use a standard 1/2 NPT nipple. A NOTICE. Unless you trim the trim plate, it will not fit a standard NPT nipple. Generally very satisfied, they look great and are good value. The knockout punch costs about $30.
