The Speed-Master® 500 is a high speed roll-up door designed for interior doorways, up to 10 feet wide x 12 feet high where environmental separation is desired and the “bells and whistles” normally incorporated into high speed roll-up doors are not required. Many of the same reliable, low-maintenance Speed-Master features have been incorporated into the Speed-Master 500: Direct-drive motor; low-profile heavy-duty steel side tracks and springless design; bottom reversing edge and reversing photo cells. Flexon Inc. manufactures the Speed-Master high speed roll-up door as well as the Flexidoor® Series of impact doors, Flexidock® loading dock equipment and the original Insect Control Barrier.®
