This is a batch of ten 9-foot glossy black coil cords with short tail that matches the color used in AT&T 900 series phones, many Avaya phones, NEC Dterm Elite phones, and Comdial DX-80 phones, among others.  They are perfectly compatible with any other phone, since it has the standard 4-conductor 4P4C handset connector sometimes also known as RJ9 that fits the majority of phones produced.  At rest the coil cord is 15 inches long (not including tail), the 9 foot measurement refers to the amount of cable used before it undergoes coiling.  This item is new and comes with a 30-day warranty!
