Product Features

Designed for 4-Sided Faceplate Installations

This bottom faceplate backing plate is specifically engineered to complete four-sided faceplate configurations for the Osburn Matrix-I wood-burning fireplace insert. It ensures full coverage of the fireplace opening, eliminating visible gaps beneath the insert.

Available in Two Width Options

Choose the correct size based on your faceplate configuration:

• AC01321 – 44" x 6" bottom backing plate
• AC01333 – 50" x 6" bottom backing plate

These sizes correspond with the standard and large Matrix-I faceplate backing plate kits.

Seamless Integration with Matrix-I Insert System

This component installs directly to the faceplate backing plate assembly during installation. According to the installation instructions:

• The bottom backing plate (AC01321 or AC01333) aligns with the inner bracket holes.
• Secured using manufacturer-specified hardware.
• Required when installing full perimeter faceplate configurations.

Professional Fit & Clean Finish

For homeowners upgrading to a modern wood-burning fireplace insert, finishing details matter. This steel backing plate ensures:

• Full coverage of the masonry fireplace opening
• Clean, flush faceplate alignment
• Improved overall aesthetic
• Proper structural support

Required for Projection Kit Installations

If your Matrix-I installation requires a 2" or 4" projection kit (AC01323), this bottom backing plate works in conjunction with:

• Faceplate backing plate kit AC01322 (29" x 44")
• Faceplate backing plate kit AC01332 (29" x 50")

As specified in the manufacturer's instructions, the projection kit must be secured to a compatible backing plate kit.
