Masterack started as the metal fabrication division of the Southern Spring Bed Company in Atlanta, Georgia. During the Great Depression, they branched into other markets beyond bed springs, which included fixtures and displays of all types for the beverage industry, and welded wire shelving for a local telephone company to install in their service vans. In 1972, Masterack patented the original roof-mounted clamping ladder rack, which quickly became the industry standard for utility vehicles of all types, from cargo vans to station wagons.
When Masterack was purchased by, Leggett & Platt, Inc. in 1972, the renewed financial backing of L&P enabled the company to expand the truck equipment business beyond the local telephone company. The ladder racks and "KD" shelving packages began to appear in service vehicles all over the country.
The next three decades saw rapid change and growth at Masterack. The company began installing van interiors and pickup caps at a facility down the street from the manufacturing plant, and then opened new facilities around the country to provide nationwide ship-through installation. The manufacturing plant was constantly upgraded and expanded into the 406,000 square feet that it is today.
In 2000, Leggett & Platt purchased Crown North America and created L&P Commercial Vehicle Products. Crown brought over 50 years of experience in the utility vehicle business, access to the Canadian market, and expanded capabilities and expertise as a Tier I supplier to the automotive OEM's. That expertise helped Masterack to achieve ISO-9001 certification in 2001.
