Syston 18/3 Thermostat Wire, 20 mil, LVT FT4, 75 m (250 ft)

Syston 18/3 thermostat wire for thermostat controls, heating and air conditioning equipment, doorbells and other low-voltage circuits.

The FT4 riser rating covers vertical runs between floors as well as general building use. The jacket is sunlight resistant (UL 1581) for above-ground outdoor runs; Syston notes it is not a substitute for direct burial cable. It ships on a Syston RhinoPac spool, designed to keep cable from tangling and to protect it from crushing and water damage. A ripcord under the jacket speeds up stripping. Ascending and descending footage markings make it easy to see how much cable is left. Legend markings let you label channels, rooms and zones.
