48" x 48" Fire-Rated Insulated Access Door with Flange - Stainless Steel

Experience unparalleled safety and access with a BA-PFI-SS 48" x 48" Fire-Rated Insulated Access Door with Flange - Stainless Steel from Best Access Doors. 

Reasons to Choose BA-PFI-SS

Unmatched Durability and Construction: Crafted from heavy-duty 20-gauge stainless steel for the door and a robust 16-gauge stainless steel frame, this access door ensures steadfast durability. The stainless steel 304 #4 brushed finish not only enhances its aesthetic appeal but also provides exceptional resistance to corrosion, promising longevity, and a polished appearance.

Security and Ease of Use: Equipped with a self-latching tool-operated slam latch and a ring-operated slam latch, this access door guarantees secure closure and effortless access. The continuous piano hinge, strategically positioned on the second dimension (height), ensures smooth operation without compromising structural integrity.

Top-Tier Fire Resistance: Featuring a substantial 2-inch-thick fire-rated mineral wool insulation, this access door meets rigorous standards, including UL 10B (2009), NFPA 252 (2012), CAN/ULC S104 (R1985), and CAN/ULC S104 (2010). Achieving an impressive 3-hour fire rating under neutral/negative pressure conditions, it's built to withstand temperatures up to 250°F after 30 minutes and 450°F after 60 minutes in vertical wall assemblies.

Certified Performance for Vertical and Horizontal Use: For vertical wall assemblies, certifications such as UL 10B, NFPA 252, and CAN/ULC S104 ensure compliance and safety. In horizontal ceiling assemblies, certificates like ASTM E119 and CAN/ULC S101 confirm a 3-hour rating in non-combustible construction and 1-hour in combustible construction. The maximum sizes for each application are clearly defined, maintaining safety standards without compromise.

Critical Safety Features and Pristine Delivery: All doors larger than 12" x 12" come standard with mechanisms allowing panels to open from the inside, prioritizing occupant safety. Each access door is individually wrapped, ensuring pristine condition upon delivery and installation.
