Power and control cables are mounted onto cable trays using special ties, attached to the tray slots. The tensile strength of these ties is 120lbs. If you need an even more secure solution, where the cable weight is greater or the cables are mounted in vertical routes, use stainless steel ties with a strong ball lock. These ties are made of acid-resistant 316L stainless steel, resistant to fire, UV, salt and corrosion. Their minimum tensile strength is up to 300lbs. In addition, they can be coated with a black or red polyester layer. An external polyester layer and gently rounded edges protect the cable from damage and prevent corrosion.
