Prior to designing our own line of products. We did sell products by Antech, Guardian Traffic Systems, and DoorKing. We began to manufacture our own, especially since other manufacturers’ products proved to be inferior. A main supplier had refused to honor a serious warranty issue which, as a result, we honored on our own. We protected our customer at our own expense. We respect our customers! Everyone works hard for their money and, in conclusion, you deserve to get what you pay for.

What is an Access Control System? Tire killers, shredders, parking gate, elevator, or other physical barriers are access controls. As a result of where granting access can be electrically or automatically controlled. Access controls are governed electronically.  Hydraulic systems leak.   Consequently, we avoid the use of hydraulics.
