The standard length of the shower arm is 40 cm (excluding the threaded connection), which saves space. The shower arm is made of 304 stainless steel, which is light and sturdy, saves space, and has a maximum load capacity of 50 kg. The shower arm connection interface fits standard 21 mm (G 1/2) threaded shower connection holes. The J-shaped stainless steel shower arm is connected to the shower head, which can highlight the bathroom. The round shower arm wall bracket (flange) has a large load-bearing surface, is firm and stable, and does not pose any safety hazards.
