East Coast Cable Ties

Black cable ties are your best option if you have an outdoor application with cables or wires exposed to ultraviolet (UV) light. They are made from a polyamide containing a black additive, which has the benefit of making them UV resistant. White cable ties, on the other hand, are perfect for indoor applications.
The traditional material for cable ties is nylon 6/6, which has a UL 94V-2 flammability rating, a high operating temperature range and pliable strength. Use them to reduce clutter on-site and keep wires from getting tangled or twisted.
