Review on 16-Inch Shower Arm Extension Extender - KES Stainless Steel Matte Black PSAN4-BK With Flange by Jay Matlock

Nice long shower arm. The unit is chrome plated with standard US fittings. The plate which covers the threads (and the hole in the wall through which you screw this into your plumbing) is unusual in that it only fits over the round exposed threads of the shower arm. This is a problem unless you are very lucky (I wasn't) as the threaded portion will be either too short or too long for a tight fit of the plate against the wall. I took a dremel tool and changed the hole in the plate from round to square so that it slides up and down the shaft of the shower arm allowing me to tighten the arm adequately and get a tight fit against the tile wall.
