DOORS: COILING SERVICE DOORS
• Coiling doors may me operated manually, by hand chain, by hand crank or by motor operation.
• Labels are available on doors up to 120 sq. ft. with no greater dimension than 12'-0" in width or height. Oversize certificates can be furnished for doors up to 576 sq. ft. with no greater dimension than 24'-0" in width or height.
• Rolling Steel Fire Doors can be installed on openings requiring fire labeled closures.

Under normal usage they operate with the same ease as service coiling doors. Thru wall fusible links are available upon request.
