Dimplex 42" Four Piece Installation Trim - For BF39DXP and BF39STP Fireboxes

Frame and complete your fireplace installation with the Dimplex 39-Inch 4-Piece Decorative Trim Kit.

The Dimplex 39-Inch 4-Piece Decorative Trim Kit (BF4TRIM39 / X-BF4TRIM39) provides a clean, professional border for compatible 39-inch built-in electric fireboxes. Designed to bridge the gap between the firebox chassis and surrounding wall materials, it delivers a sleek 3-inch black metal surround that frames the flame display. It serves as an ideal architectural solution for homeowners seeking a minimalist finished hearth and installers looking to simplify drywall, tile, or stone cutouts.

Key Benefits

• Clean Finished Border – Conceals rough wall cutouts and gaps between the firebox and surrounding drywall or masonry.
• Sleek 3-Inch Profile – Features a 3-inch black metal frame that provides a low-profile, architectural edge around the firebox.
• Minimalist Hearth Styling – Allows for a clean, mantel-free installation that puts full visual focus on the flame display.
• Durable OEM Construction – Crafted from heavy-duty painted steel engineered to withstand heat and maintain a rich black finish.
• Direct Firebox Compatibility – Fits precisely onto Dimplex 39-inch BF Series built-in fireboxes without custom fabrication.
• Fast 4-Piece Assembly – Interlocks smoothly around the firebox perimeter for effortless, time-saving job site installation.

Seamless Architectural Finish

By covering raw wall edges and uneven cutouts, this 4-piece metal surround creates a crisp, intentional transition from wall to fireplace. Homeowners achieve a sleek, high-end focal point that pairs effortlessly with tile, stone, stucco, or painted drywall.

Durable Metal Construction

Built with solid steel components in a satin black finish, the trim kit offers long-lasting structural rigidity and clean aesthetic performance. Installers benefit from precision-engineered alignment that eliminates the need for expensive custom metal fabrication or framing adjustments.

Precision OEM Fit

Designed directly by Dimplex for 39-inch BF Series built-in fireboxes, the 4-piece kit attaches directly onto the outer cabinet frame. This ensures a tight, flush fit that simplifies finishing work for both new construction and remodel projects.
