The cable holder is made of stainless steel and comes powder coated in black. On the back is a strip of neoprene rubber to protect any paint on the post to which the holder is mounted. The neoprene rubber also helps to keep the cable holders in place. The straight mounting kit, Ø60 for double cable holder is made of stainless round steel with an attached black rubber hose. This is to protect any paint on the post and also to keep the cable holders in place.
