The KRP-150FR is an insulated, flush mounted fire rated access door designed for installation in walls and ceilings. It has mounting holes to facilitate installation and is listed by Underwriters Laboratories for a 1.5 hour “B” label in walls and by Warnock Hersey for 3 hours in ceilings.
For architects, contractors and specifiers, the important point is that the fire rating is specific to the KRP-150FR and its listed application. Select the door based on the rated assembly, location and required opening protection rather than treating all fire rated access doors as interchangeable.
The KRP-150FR provides access to services located behind a rated wall or above a rated ceiling while maintaining the required listed protection at the access opening.
Typical applications can include:
The access door should be positioned and sized so the required equipment can be reached while remaining within the product's listed size and installation requirements.
The KRP-150FR has different listed ratings depending on its location. It carries a UL 1.5 hour “B” label rating in walls and a Warnock Hersey 3 hour rating in ceilings.
That distinction matters when specifying a fire rated access panel. A rating for one location should not automatically be assumed to apply to another. Always match the KRP-150FR specification and listing information to the rated wall or ceiling assembly shown on the project documents.
For projects with different surface or installation requirements, Karp also offers other fire rated access doors, including the KRP-350FR, KRP-250FR and KRP-450FR.
The KRP-150FR uses a flush-mounted design, making it suitable where a conventional exposed frame is appropriate for the finished wall or ceiling surface.
Masonry straps are included on Karp fire rated applications for securing the installation in masonry construction. Where a project requires a different finish or drywall-concealed flange, select the fire rated model designed for that surface rather than modifying the KRP-150FR.
KRP-150FR is available in a range of standard sizes from 8 x 8 inches through 48 x 48 inches. The published size table identifies the corresponding wall or ceiling opening for each door size.
The opening dimension is not the same as the nominal door dimension. For example, an 8 x 8 inch KRP-150FR requires an 8 3/8 x 8 3/8 inch wall or ceiling opening.
Always use the published opening dimensions and the applicable product documentation when preparing the rough opening.
A fire rated access door should be selected as part of the rated assembly rather than simply because a wall is labeled “fire rated.” Verify the required rating, wall or ceiling location, door model and permitted size against the project drawings and Karp's current specification documentation.
Karp provides architectural specifications and technical documentation for its fire rated access door models to support specification and submittal work.
For additional guidance, see Karp's resource on fire rated access doors, requirements and ratings.
