Our Security Series Roof Access Hatch is constructed with heavier gauge materials for application in public buildings, prisons, banks, embassies and pharmaceutical buildings where a high level of security is required at access points to and from the roof.
Security Series Roof Access Hatches can be fabricated for field installation of many leading brands of security locks. Other options include security glazing and gunports (shown with optional detention lock, security glazing, and Tnemec finish).
Engineered with compression spring operators to provide smooth, easy, one-hand operation, regardless of hatch size.
Automatic hold-open arms lock the cover open to enable safe egress.
Overlapping cover design, fully welded corners on covers and curb, EPDM rubber gasket, fully insulated cover and curb ensure the Roof Access Hatch remains weathertight and energy efficient.
Constructed with corrosion-resistant materials to provide many years of trouble-free, dependable service.
Heavy gauge construction and positive latching mechanism maintain building security.
Available in many sizes and curb configurations to satisfy any requirement or installation.
