Elmdor ACC24 Drywall Access Door 24 X 24 in

Product Description

The ELMDOR ACC24 is a drywall access door designed to provide service access to concealed mechanical, plumbing, and electrical systems behind finished wall or ceiling surfaces. Built to flush-mount into standard drywall assemblies, it gives HVAC technicians, plumbers, and electricians a clean, re-openable entry point to valves, cleanouts, junction boxes, and other components that require periodic inspection or service. The panel measures 24 inches x 24 inches, making it suitable for applications where a larger access opening is needed. Installation is handled by general contractors, finish carpenters, or the responsible trade during rough-in or finish phases of construction.

The ACC24 is used in residential and light commercial construction wherever concealed infrastructure must remain accessible after walls or ceilings are finished. Typical installations include mechanical closets, above dropped ceilings, behind tub and shower surrounds, and along chase walls housing ductwork, piping, or conduit runs. The 24-inch by 24-inch opening is large enough to allow hands-on service work without requiring destructive wall removal.

Key Features

• 24 inches x 24 inches opening provides generous access to concealed systems
• Designed for flush installation in standard drywall assemblies
• Re-openable panel allows repeated service access without wall damage
• Suitable for walls and ceilings in residential and light commercial applications

Compatibility

Designed as an OEM-style replacement and new-installation access door for standard drywall wall and ceiling assemblies requiring a 24-inch x 24-inch rough opening.

Installation Notes

Installation is typically performed by a licensed contractor or the responsible trade during the finish phase. The rough opening should be framed to the manufacturer-specified dimensions before the door frame is set. Always shut off power to any electrical systems and shut off water or gas supply to any plumbing or mechanical systems accessible through the opening before beginning service work. Local building codes may require specific fire-rated assemblies in certain wall types — verify requirements before installation.
