Need a Custom-Size Access Door?

Standard sizes do not work for every opening or application. Best Access Doors offers custom-size access doors, panels, roof hatches and floor hatches manufactured to meet your project’s specific dimensions and performance requirements.

Whether you need a non-standard size, specific material or a specialized configuration, our product experts can help you identify the right custom access solution.

What Can Be Customized?

Depending on the product and application, available options may include:

  • Width and height
  • Wall, ceiling, or floor application
  • Steel, stainless steel, aluminum or other available materials
  • Flange and frame style
  • Locking and latching options
  • Insulation and weather resistance
  • Fire-rated configurations
  • Finishes and special project requirements

Not every option is available with every model or certification. Our team will review your requirements and help determine the appropriate solution.

When Should You Request a Custom Size?

A custom access product may be appropriate when:

  • The opening does not match a standard product size
  • Plumbing, electrical or HVAC systems limit the available space
  • The project requires specific materials, finishes or locking options
  • A wall, ceiling or floor assembly has unique installation requirements
  • You need a product for a specialized commercial or industrial application
  • You cannot find a standard model that meets the project specifications
