The Henderson Sprint provides a high performance at a surprisingly low price. There is 1 Sprint model - the 550SL for doors up to 14 ft wide The unique gliding motor keeps moving parts to a minimum, reducing noise and making the system maintenance-free An in-built safety sensor detects any obstruction to the door movement, stopping the door and reversing if on the closing cycle An in-built light on the back of the unit automatically switches on as the door opens and switches off after 3 minutes The Sprint memorises the time taken to open and close the door and then ensures a softer start and stop to the movement (so there's less door slam)

Two stylish handtransmitters are supplied, each with four buttons (so they can operate more doors, gates or security lights) with a 'rolling code' security system with 74 trillion code options A wall mounted push button is provided to site up to 7m away from the unit as another means of opening the door. In addition, every Sprint has a simple switch to allow manual operation from inside the garage. |
