Product Spotlight

What Is the KRP 150FR Fire-Rated Access Door?
The KRP 150FR Fire-Rated Access Door is an insulated steel access panel engineered for installation in fire-rated walls and ceilings. Unlike standard access doors, this model helps preserve the integrity of a fire-rated assembly while still providing maintenance personnel with convenient access to plumbing, electrical, HVAC, and communication systems.
Because many commercial buildings contain hidden utilities that require periodic inspection and maintenance, fire-rated access doors play an important role in both safety and building operations.
Key Features
The KRP 150FR offers several advantages for commercial construction projects.
- Insulated fire-rated construction
- Durable steel design
- Available in multiple sizes
- Designed for wall and ceiling installations
- Helps maintain the fire rating of the assembly
- Manufactured by Karp Associates, a trusted commercial building products manufacturer
These features make the KRP 150FR an excellent choice for architects, contractors, facility managers, and building owners who need dependable long-term performance.
Where Is the KRP 150FR Commonly Used?
Fire-rated access doors appear in many commercial buildings because building codes often require fire-resistant assemblies in specific locations.
Common applications include:
- Hospitals
- Schools
- Commercial office buildings
- Government facilities
- Mechanical rooms
- Stairwells
- Utility spaces
- Institutional buildings
Whenever maintenance personnel need access behind a fire-rated wall or ceiling, a properly tested fire-rated access door helps preserve the assembly’s performance.
Why Choose a Fire-Rated Access Door Instead of a Standard Access Door?
Although standard access doors work well in many applications, they cannot maintain the fire rating of a wall or ceiling.
A fire-rated access door provides several important benefits:
- Maintains fire-rated wall and ceiling assemblies
- Supports building code compliance
- Protects occupants by slowing the spread of fire
- Allows routine maintenance without compromising fire protection
- Provides long-lasting durability in commercial environments
As a result, many architects specify fire-rated access doors whenever building codes require rated construction.
