What are counter doors, and where are they used?
Counter doors, also called counter shutters, are ideal for concession areas, cafeterias, pharmacies, cashiers, parts, and tool storage. They secure openings on interior and exterior walls without requiring flame or smoke resistance.
What materials are counter doors made from?
Standard counter doors use aluminum or galvanized steel slats, while fire-rated versions utilize 22-gauge steel or 300-series stainless steel for durability and safety. Powder coating or anodized finishes are also available.
Do counter doors come in fire-rated options?
Yes, Clopay offers fire-rated counter doors with UL classifications of ¾ HR, 1 HR, 1½ HR, and 3 HR, providing added protection for openings where fire safety is required.
What sizes are available for counter doors?
Standard counter doors can fit openings up to 21’ wide by 10’ high, while fire-rated doors accommodate openings up to 16’ wide (depending on height) or 10’ wide for smaller models.
How are counter doors installed?
They can be mounted face-of-wall or between-jambs in interior or exterior walls, compatible with masonry, drywall, or steel construction. Some models come with integral frames for easier installation.
What operation methods are available?
Counter doors can operate manually with push-up or hand crank systems, or motorized for larger openings. Concealed tubular motors are available for compact or aesthetic installations.
Are smoke control or countertops available with fire-rated doors?
Yes, optional UL-classified smoke seals prevent smoke infiltration, and fire-rated countertops can be made of plastic laminate or stainless steel to meet safety standards.
