 The switch to Revco is on. More contractors are making the switch to Revco lighting and electrical supply. It's easy to see why. This is Mark Fink of Fifth Generation Electric. I come from a long line of electricians, and to this day, we still use Revco, the best supply house on the island. Revco is where you'll find unmatched customer service, a knowledgeable sales staff, and high-quality product in stock when you need it. Revco now has six locations in Suffolk. The switch to Revco is a quote away.
