36" x 48" Fire Rated Access Door for Walls - Karp

36" x 48" KRP-150FR Fire Rated Access Door for Walls and Ceilings - Karp

Open wall and ceiling spaces can allow fire and heat to spread quickly, increasing damage and making it harder to manage. Without a fire-rated access door, these openings can weaken under extreme conditions.

The 36" x 48" Fire-Rated Access Door – KRP-150FR is built to slow down fire and heat for up to 1.5 hours on walls and 3 hours on ceiling, helping to maintain the strength of fire-rated barriers.

Its self-latching mechanism keeps the door securely closed, while 2-inch-thick fire-rated insulation reduces heat transfer, improving performance in high-temperature conditions.

Why Choose the 36" x 48" KRP-150FR?

• Helps Meet Fire Code Requirements: The KRP-150FR is ideal for commercial projects that require a reliable fire-rated access point in walls and ceilings.
• Built to Last: Constructed with 16-gauge steel and a welded pan-type door, offering lasting performance in demanding environments.
• Secure Closure: Its self-latching mechanism ensures the door stays shut when needed.
• Reduces Heat Transfer: With its insulated core, this access door helps maintain interior temperatures.
• Easy Installation: Thanks to its flush-mounted design with pre-drilled mounting holes, the KPR-150FR is easy to set up.

Installation Instructions

1. Prepare the Opening: Mark and cut a 36 3/8" x 48 3/8" rough opening in the wall or ceiling. Ensure the framing is properly reinforced to support the door’s weight and fire-rated integrity. If installing in masonry, have the included masonry straps ready.
2. Position the Access Door: Place the KRP-150FR into the opening, ensuring the frame sits flush with the surface. Use the pre-drilled mounting holes to align the door properly. For ceiling installations, double-check that the door’s weight is fully supported.
3. Secure the Frame: Fasten the door frame using fire-rated screws, ensuring a tight and stable fit. For masonry applications, attach the included straps securely to the structure. Verify that the door remains level and opens smoothly before fully tightening the screws.
4. Final Adjustments and Finish: Check that the door self-latches and the keyed paddle latch functions properly. If necessary, make minor adjustments to ensure smooth operation. Once secure, apply a fire-rated sealant around the frame if the code requires it, and then finish the surrounding wall or ceiling as needed.
