Lexington Grist Mill Series Fireplace Non-Combustible Mantel
The Grist Mill mantel is molded from a 6" x 5.75" beam salvaged from an old Kentucky barn, with the weathered look of the timbers in old water-wheel grist mills. The casting carries deep woodgrain, tool and saw marks, checks, splits, knots and insect damage.
It is cast in Burncrete and hand-painted in Lexington, Kentucky, in five colors. Model number GM-4-LH (48"), GM-5-LH (60") or GM-6-LH (72"), followed by the color code.
Grist Mill: Barnwood Character for Wood, Gas or Electric Fireplaces
Lexington rates the Grist Mill for wood-burning, gas and electric fireplaces, and its ASTM E136 certification lets it sit closer to the heat than a wood beam. Lexington's install guide calls for at least 6" of clearance above equipment under 50,000 Btu and 12" at 50,000 Btu or more; your fireplace's clearances and local code come first.
At 52 lb in the 48" length, it is the lightest of the 48" beams in the line, and the hollow core mounts on a framed wall with the included bracket. Set it over a wood burning fireplace or browse the full Lexington Hearth collection.

FAQs
Can I get the Grist Mill in a custom length or color?
Yes. Lexington makes custom lengths between 48" and 72", and shorter on request. Past 72", add the 2 ft extension and bracket trim. Burncrete should not be cut or sanded on site, so order the length you need. Custom colors are matched at the factory. Reach out to our team for a quote.
How is it installed?
With two people and basic tools. Screw the bracket into the studs (2 for the 48", 3 for the 60", 4 for the 72"), set the mantel on it, drive three screws down through the top, then fill and touch up the holes. For walls other than wood framing, consult a professional.
