Founded in Pittsburgh in 2005 by Vietnam veteran Briane Hartley, Door Guard Inc. manufactures made-in-America elevator protection systems that shield cabs and building interiors during moves, deliveries, and renovations. Its custom-fit liners use a patented locking system for fast installation while keeping elevators operational, a practical alternative to repairing a damaged cab. The company says its products now protect more than 1,000 buildings nationwide.
