We thoroughly test our equipment so your products perform exactly as specified.

Commercial rolling and sectional doors, high-speed doors and residential overhead doors provide safety, reliability and convenience for millions of applications everyday. They are expected to open and close quickly, quietly and without fail and that’s why the right transformers and contactors are critical components in this market. Manufactured from quality materials, our contactors and transformers provide years of reliable operation in any environment factories, multi-unit dwellings and residential applications. Purposefully engineered and tested, our contactors open and close quietly. SPL engineering, testing and quality teams know your reputation is on the line every time an overhead door opens and closes, so you can be assured of our commitment to quality.
