Southern Lock began in the home of Bernard and May Cutson in 1946.

Two years later as their company grew, the business was moved to the family garage, then to its first storefront in south St. Petersburg, and finally to its present address, a 19,000 square foot warehouse.

In the 1970s, watts lines were installed and “S-Line” products soon followed. Southern Lock also established an in-house advertising department and yearly catalog. In the 1980s, the building was expanded to include a large Customer Service area, computer system, and Electronic Access Department. To remain on the cutting edge, Southern Lock also launched their first website.

Over the years, satellite locations have been opened in Pompano Beach, and Charlotte, NC. Today the company is owned and operated by David Matthies, first employed by the company in 1970, and David Swartz, who started in 2007. Dave and Dave purchased Southern Lock from then-owner, Marvin Cutson, on March 1, 2011.

From the earliest days to the present, the company's goals have remained the same: to provide customers with quality products and the best service possible. Whether placing, pulling or shipping an order, our qualified group of employees work together to handle all jobs in an efficient and pleasant manner. Southern Lock stands as a leader in the security hardware industry and will continue to grow and evolve with our ever-changing world.
