Commercial door operators offer great convenience by allowing you to operator your door with the push of a button. But that's not all! Did you know that a door operated by an electric operator will last longer and work safer than a manually operated door? It's true. The smooth operation allows the door to run consistently every single cycle. Plus, all of our operators meet UL325 which means they come with a monitored safety device standard. Controls can be as simple or complex as you like. Smartphone compatibility is an option on all models. K.J. Door Services, Inc.  is a ProVantage Liftmaster dealer, which means you get the very best product and warranty support. Below is a link to Liftmaster's™ website, along with the commercial models we keep IN STOCK.
