If you're ever looking for a roof hatch, make sure you have the BA-VM roof hatch installed in your buildings.
You can install this type of roof hatch if you have a damaged roof hatch that needs replacing. It's as easy as removing the cover from the broken hatch and placing it on top of the existing curb.
You can choose the roof hatch material, such as aluminum, steel, or stainless steel. You'll be glad to know that the materials are corrosion resistant, which grants the building years of being maintenance-free.
You don't have to fret about any illegal breach because of the heavy gauge construction and positive latching mechanism in terms of security.
The cover is a brake-formed, hollow-metal design with 1" (25 mm) concealed fiberglass insulation, 3" (76 mm) beaded, overlapping flange, fully welded at corners, and internally reinforced for 40 psf (195 kg/m2) live load.
For construction contractors who need specific measurements, the BA-VM comes in various sizes and curb configurations for them to choose from.
Material: 14 gauge (2 mm) G-90 paint bond galvanized steel cover and frame
Finish: Alkyd base red oxide primer
Gasket: Extruded EPDM rubber gasket permanently adhered to the cover
Hinge: Heavy-duty pintle hinges with 3/8" (9 mm) type 316 stainless steel hinge pins
Lock / Latch: Slam latch with interior and exterior turn handles and padlock hasps
Lift Assistance: Compression spring operators enclosed in telescopic tubes. Automatic hold-open arm with grip handle release.
Hardware: All hardware is zinc plated/chromate sealed.
