About Ledge Access Panels - Technical Specifications and Product Information

Made of glass fiber reinforced gypsum (GFRG), our access panels are the newest offering in our Ledge Products line of GFRG and GRFC products. The panels are some of the highest quality available on the market today and are ideal for any location. Ledge access panels blend seamlessly into ceilings and walls to provide convenient access to building components.

The following specifications and product details provide an overview of our Ledge access panels. We are also available to answer any questions you may have as you choose the appropriate panel for your needs. 

Sizing for Our Standard Access Panels

The sizing for an access panel is determined by the door opening dimensions. The rough opening where the panel will be installed will generally have an additional 6” on these dimensions. Standard door opening sizes and weights are:

9” x 9” - (4lbs)

12” x 12” – (6 lbs.)

16” x 16” – (8 lbs.)

18” x 18” – (9 lbs.)

24” x 24” – (12 lbs.)

22 ½” x 30” – (15 lbs.)

30” x 30” – (19 lbs.)

Custom sizing is available on request and is suitable for larger projects. If you would like to special order a custom size, please contact us.

Door Design

All of our access panels use either a hinged or drop-in door. Hinged access panels can be used on either wall or ceiling installations, while drop-in is for use on ceiling panels. Both options are available on any size access panel.

Installation and Framing

The access panel should be securely attached to studs or blocks during installation. Regular framing is not required for the panel itself and framing of the rough opening will depend on the standards of the job-site.

Panels are installed with #6 bugle head screws The connection between the drywall around the opening and the panel can be covered with joint tape which can then be sanded and finished so that the appearance is cohesive with the property.

Finishing Options

Standard access panels are gypsum based with a natural off white color that can be painted to match the ceiling color. All finishing work should be done by the installer.

For external use, cement based (GFRC) access panels should be used to offer better durability against the elements. We are able to create cement access panels on special request.
