## Long description

AWENTA model kral21 access panel for drywall 400×500 mm is a metal inspection door designed to be installed in gypsum board partitions with a 400×500 mm opening. The panel features a flush cover that can be finished with gypsum and painted to match interior surfaces, providing discreet access to service zones, concealed utilities and installations behind walls. The construction is intended for residential and commercial interiors where regular or occasional access to plumbing, electrical or ventilation components is required without compromising wall finish.
Advantages
The unit provides a low-profile, paintable finish that integrates with drywall surfaces. Durable metal construction ensures stable frame alignment and reliable closure. The panel allows concealed access while maintaining a smooth wall appearance once finished with gypsum and paint. Installation minimizes visible gaps and supports maintenance access without removing large sections of wall.
Suitable for
Access to plumbing fixtures and shut-off valves concealed in drywall
Inspection and maintenance of electrical junctions and service boxes behind gypsum board
Access to ventilation dampers, filters or controls located within wall cavities
Service access in residential bathrooms, kitchens and commercial interiors
Key specifications
Designed opening size: 400×500 mm compatible with standard drywall cut-outs
Material: metal frame and cover suitable for finishing with gypsum and paint
Flush cover design to provide a flat surface for plastering and painting
Intended use: indoor installation in gypsum board partitions
Provides concealed, service-style access to installations behind walls
How to use
Cut a 400×500 mm opening in the gypsum board at the planned location and ensure the surrounding structure is level and capable of supporting the frame. Insert the metal frame into the opening and secure it to the partition structure according to mounting points, verifying that the frame is square and flush with the board surface. Apply gypsum compound or plaster over the cover to achieve a smooth finish, allow to dry, then sand and paint to match the wall. The panel is then ready to provide concealed access; open the inspection door when needed for maintenance or inspection of utilities behind the wall.
Usage recommendations
Install the panel before final decoration and apply finishing layers carefully to maintain door functionality. Ensure the opening and frame remain unobstructed by insulation or wiring that could prevent closure. For frequently accessed service points, consider leaving a slightly looser finish to prevent repeated plastering from damaging the panel edges.
