About Us

Company Founding

Enclose Manufacturing Inc. was founded in 1998. Enclose Manufacturing Inc. is a small sheet metal manufacturing business, located in South Dakota as an OEM manufacturer, of Traffic cabinets and Industrial Enclosures. Our Traffic Cabinets are for ITS, DMS and VMS uses and other Traffic control applications. Over the last 18 years we have provided a bare cabinet unit meaning no electronics or power supplies were being supplied. However due to increased demand to supply a more complete cabinet we began offering LIMITED electronics and power apparatus and wiring such as Thermos Protection, Lighting and 110V/24V power supply units with surge protection. Load Center Controls, Power Strips, UPS units, and much more.

Enclose Manufacturing Inc. also builds a wide variety of industrial enclosures that are used in many industries throughout the USA and Canada uses range from Industries such as AG, Mining, Energy, Telecommunications’ and Manufacturing. We pride ourselves in being a USA Made products manufacture with the best quality and competitive pricing available today. Our stream lined manufacturing processes allows us the capacity to have one of the shortest lead-times in this industry. Our typical turnaround time is the shortest compared to our competitors. We excel in custom cabinet designs that are specific to the customers’ needs and specifications. The initiatives derived from our QC team and Lean manufacturing principals are team driven partnerships that drives a continuous need for improvement and cost added value that goes into every cabinet or enclosure produced.
