Concealed Access Doors

Where concealed access panels are specified

A concealed access door is specified when the client does not want to see a door. The panel takes the same finish as the surrounding surface, so once the wall is taped, skimmed and painted the only thing marking the opening is a hairline joint. Architects use them in lobbies, guest rooms, galleries and any ceiling where a row of visible panels would read as clutter.

Three ways a panel is concealed: recessed, GFRG and aluminum framed

Three approaches, depending on the finish being matched.

Recessed doors leave a rebate in the panel face that accepts drywall infill on site, so the panel is finished by the same trade that finishes the wall. The RDW covers drywall surfaces and the RDWPD arrives with the drywall already installed at the factory, which removes a step on site and guarantees the thickness is right.

Glass fiber reinforced gypsum panels are made of the same material family as the surrounding board. The GFRG and the hinged FGH suit ceilings where the panel should read as continuous plaster.

Aluminum framed drywall doors, the KAD, give a fine, stable frame with a drywall face, and the CDW all drywall ceiling access panel is the ceiling equivalent.

What to coordinate before the wall is closed up

Concealed doors need the finishing trade to know they are there. A recessed panel that gets skimmed shut is no longer an access door, so mark locations on the drawings and brief the finisher. Access frequency matters too: a concealed panel is the right answer for an opening reached once a year and the wrong one for a valve that gets checked monthly, where a visible latched door is faster.

All models are made in the USA. Sizes are listed per model on each product page.

Frequently Asked Questions

What is a concealed access door?
A concealed access door is a panel designed to be finished with the same material as the surrounding wall or ceiling, so it is not visible once the surface is complete. It is used where a visible door and frame would be unacceptable on appearance grounds, such as lobbies, guest rooms and feature ceilings.
How is a concealed access door opened if you cannot see it?
Location has to be recorded. Concealed panels are opened with a tool or by pressing a release, depending on the model, and the position is normally marked on the record drawings or noted by facilities. This is the practical trade-off of concealment and the reason concealed panels suit low-frequency access rather than routine service points.
What is the difference between the RDW and the RDWPD?
Both are recessed doors for drywall surfaces. The RDW ships with an empty recess for drywall infill to be fitted and finished on site. The RDWPD arrives with the drywall already installed at the factory, which removes the site step and ensures the infill thickness matches the panel recess.
What is a GFRG access panel?
GFRG stands for glass fiber reinforced gypsum. The panel is made from the same material family as surrounding gypsum board and plaster finishes, so it takes the same paint and reads as continuous surface. Karp offers the GFRG panel and the FGH hinged version.
Can a concealed access door be fire rated?
Concealment and fire rating are separate requirements, and the concealed range is not the fire rated range. If the assembly is rated, specify from the fire rated category (KRP-150FR, KRP-250FR, KRP-350FR, KRP-450FR) and confirm the listing covers the location. Do not assume a concealed panel holds a rating.
Do concealed access doors need special installation?
They need coordination more than special skill. The frame is set like any other access door, but the finishing trade has to know the panel is there so it is finished around rather than skimmed over. Mark every location on the drawings and brief the finisher before the wall is closed up.
