18/5 Thermostat Wire — 18 AWG, 5 Conductor (Sold by the Foot)

Buy the Length You Need, Not the Spool You Don't

Most control wiring jobs need forty feet, not a five-hundred-foot spool gathering dust in the garage for the next decade. This 18 AWG five-conductor thermostat wire is sold by the foot, so you order what the run actually calls for and pay for exactly that.

Five conductors give you room for the control signals a modern ventilation setup needs, with a spare or two left over for whatever the system grows into later. The flexible white jacket pulls easily through studs and joist bays and stays inconspicuous where it surfaces near equipment.
