Here at Best Access Doors, we aim to provide the quality products you need for any project necessities. One of our best products is the BA-FRI-SS Fire Rated Access Panel Insulated in Stainless Steel. This access door is both practical and ascetically pleasing thanks to its continuous piano hinge, steel frame, and self-closing and self-locking mechanism for easy access on either side.
Contractors across North America prefer the BA-FRI-SS because of its easy access to electrical, HVAC, plumbing, and other fixtures inside your fire-rated walls or ceilings. The BA-FRI-SS offers a 16-gauge cold-rolled steel frame and 20-gauge galvanneal steel door, 2-inch mineral wool for fire-rated insulation, a continuous piano hinge, an inside panel release standard on all doors over 12" x 12". As an added benefit, this access door also provides an easy to operate automatic panel closer (which is standard on all FRI-SS doors). This access door is finished with DuPont's high-quality white powder coat, which you can paint right after installation is complete!
For installation in vertical wall assemblies, the FRI-SS insulated access door has a fire rating of up to 3 hours. Whereas, for installation in horizontal ceilings, the fire rating measures up to 3 hours in noncombustible construction and a 1-hour fire rating incombustible structure. We also offer a wide variety of custom latch options. For the FRI-SS, the door comes standard with a ring/tool key operated slam latch and can also be equipped with a key-operated cylinder cam latch, 4" handle operated slam latch, hex head slam latch, and mortise slam latch.
Our fire-rated access panels are made of high-quality materials and meet NFPA standards. Another benefit of installing our FRI-SS fire-rated door is that it can contribute directly to a project's ability to achieve LEED certification in new construction and significant renovations such as schools and commercial interiors.
