Single and bi-parting door operating systems are available for commercial/industrial doors weighing 500 lbs to 125,000 lbs!
    We manufacture a variety of heavy duty ball screw and timing belt drive systems specially designed for a large range of operating forces (300 lbs- 1800 lbs), and linear speeds ( 4.5 in/sec – 18 in/sec) for unlimited travel distances.
    All systems are fully compliant with UL325 for commercial/industrial doors operators. 


    Notations for item table below:

    1. Recommended for door weights listed, provided the Max. Operating Force (MOF) has not been exceeded. Door weight must be fully supported by track or bearing system. Door Operator shall not support any hanging door weight.
    2. Max. Operating Force (MOF) includes total force to overcome door friction, door track misalignment and acceleration forces.

    3. Features Linear Guide Tracking System, which supports timing belt and allows quick disconnect for manual operation.

    4. Door weights and Operating Forces can be increased by decreasing speed. Please contact the Engineering Department
