This Shower Arm is made of Brass with a polished 'mirror' chrome finish.

It has 1/2" BSP threaded ends (measuring 3/4" diameter) and is approximately 25cms long (from the plate that sits against the front face to the tip of the shower head connection). 

There are two elbows that are secured with wing nuts. This allows the arm to be angled either upwards, downwards and allows the shower head to be tilted further. 

It comes with a securing nut and washers.
