12" x 12" Non Insulated Fire Rated Access Door for Drywall - Stainless Steel - Karp

12" x 12" KRP-450FR-SS Non-Insulated Fire Rated Access Door for Drywall - Stainless Steel – Karp

Hospitals, research labs, and food processing facilities have strict fire codes and hygiene standards. Unfortunately, property managers and contractors often struggle to find access doors that meet both requirements.

Standard steel access doors rust, corrode, and harbor bacteria in places where cleanliness is a matter of life and death. Meanwhile, many "stainless" options compromise fire ratings or ruin the design of finished drywall walls.

The 12" x 12" KRP-450FR-SS Non-Insulated Fire-Rated Access Door for Drywall - Stainless Steel solves this problem. This UL-rated stainless steel access door provides 1.5-hour "B" label fire resistance and won't corrode or harbor bacteria, giving you the easy-clean surface that hygienic environments demand.

The textured frame design lets you apply drywall compound thick enough to completely hide the flange, creating a seamless look that inspectors or building owners will appreciate.
