Duplex Electrical Supply was founded in 1990 on the North Shore of Long Island known as the Gold Coast. From the very first sale to the present-day Duplex’s #1 goal has been to service the electrical contractors’ needs.

We realize your time is valuable, so we get you in and out as quickly as possible. If you can’t make it to us, we offer same day deliveries, usually within a few hours.  We are able to turn around Lighting & Gear quotes on the same day. Backed by a 120,000-square foot Central Distribution Center (CDC), Duplex has a great fill rate and we can fill most backorders by 7:00am the following morning.

A live person will always greet you on the phone. Our motto is “WE’RE NUTS ABOUT SERVICE!” providing a bag of peanuts with every delivery.  With our knowledgeable staff and breadth of inventory, Duplex is capable of serving the one-man shop or the large project with fair and competitive pricing.   

Give Duplex a call; we pride ourselves on the ability of our knowledgeable staff to quickly and professionally service all of your electrical needs.
