LISTINGS
Motor operation is required. The Best Rolling door assembly is designed to mount to structural supports recessed within the wall construction, with the curtain coil concealed above the ceiling to minimize exposed components and potential ligature points. The motor operator is mounted above the ceiling.
Use of a ligature-resistant access panel is recommended for service access; access panel is not furnished by Best Rolling.
The control station MUST be installed within direct line of sight of the door opening to allow the operator to monitor curtain travel and prevent obstruction during operation.”

Design Options
PARTIAL PERFORATED OR GRILL
Combine perforated or grill slat section at eye-level with solid slats in the same curtain. Allows for ventilation with added security, while still being able to see into the next space.
PASS DOOR
Hollow metal doors are ideal in applications where space is too limited for the installation of a standard entry door. A pass door conserves energy by allowing building access via a smaller opening versus opening the entire door.
FAST ACTING DOORS
For high traffic openings or where air flow or temperature control is critical, doors can be designed to operate at more than twice the speed of typical doors, or up to 2 ft/sec
HIGH CYCLE SPRINGS
High Cycle performance available up to 100,000 cycles at an additional cost (i.e. parking garages, sally ports).
SLOPING FLOOR
Bottom bar design can be sloped to accommodate floor conditions that are not level. This allows for the opening to be entire secure and touch the floor at all points.
SAFETY EDGE
Addition of a safety edge to the bottom bar prevents damage to an object in the door’s pathway in addition to minimizing damage to the closure itself. If trying to close the door, the door will stop and open again.
