Our commercial garage door opener three-wire coil cord from North Shore Commercial Door is for connecting your operator's sensing edge to the operator to keep the door moving. This is 18-gauge commercial garage door opener coil wire with a 4-foot retracted length and 20-foot extended length. The coil cord, when connected to the operator, extends and retracts as the door moves up and down. If our original coil cord breaks or becomes damaged, this is the replacement coil cord you need for any brand commercial garage door operator.
Retracted length: 4'
Extended length: 20'
