At Southwire®, we continue to create quality, long lasting products for the HVAC industry. Our latest innovation, SIMpull® Tstat™ wire, combines traditional thermostat wire with patented SIM Technology® for faster installs and cleaner handling. Designed to be easier to pull, easier to strip and more resistant to abrasion, it makes tough retrofit jobs more of a breeze. And, the SIMpull® Tstat™ advantage is available at the same price as our traditional thermostat wire.
