Flex-Back Panel

The FLEX-BACKTM Panel is the answer to common lower door panel damage, which is one of the most frequent and costly maintenance problems in today’s busy warehouses. The FLEX-BACK panel is constructed of a high impact polymer skin and flexible tube frame which allows the panel to flex upon impact and return to its normal operating position. This durability helps reduce door maintenance costs and helps eliminate damage to bottom door panels. The FLEX-BACK uses standard door hardware and replaces most standard sectional door panels easily. The insulated panel also provides an exceptional thermal seal to save on energy costs.


Loading Dock Systems offers and entire line of electric operators to suit new construction and retrofit applications, as well as unusual or special requirements. Our operators afford precise control of door action for years of trouble-free operation. In order to improve safety and enhance door and motor life, industry quality assurance guidelines recommend the choice of a single manufacturer for both door and operator applications.
