Mantel is a custom-made Premier-tier fireplace door with a cast aluminum frame, welded mitered corners, and a wide 2⅝-inch top rail tuned to read as a natural transition into a wood or stone mantel shelf above. Built to tuck cleanly under tight lintels and millwork while carrying shadow under the mantel. Lead time: 3–5 Weeks after Expert Fit Review.
Options & Features
- 2⅝-inch wide top rail — roughly half an inch beefier than a standard Premier so the door reads as part of the millwork, not separate from it
- Cast aluminum Premier-tier frame with welded mitered corners, hand-dressed at the seam
- 1-inch standard overlap (Masonry) · 1/4-inch overlap (ZC) — wider top-rail overlap helps tuck the door under a tight mantel shelf
- Powder coat baked at 400°F — matte black and textured bronze suit mantel millwork best
- Tempered safety glass — Clear (default) or Bronze tint for traditional rooms
- Cabinet or bifold door style — handles deliberately understated so the mantel itself takes the architectural load
- Cabinet mesh integrated behind the frame for a clean silhouette under the mantel
- Built for masonry overlap, masonry inside fit, and prefab openings
- Custom sized in 1/8-inch increments
- Heat Shield (+$70) highly recommended on wood mantels; Integrated Hood (+$205) especially relevant with tight lintels
- Optional Custom Cutouts (+$135) and child safety clips / keyed locks (quote on request)
- Made in USA with free freight to the contiguous 48 states
- Custom-made — no returns; Expert Fit Review confirms accuracy before production
- Limited lifetime frame warranty · 90-day finish guarantee

Frequently Asked
Why does non-combustible matter?
Traditional wood mantels require a minimum 12" clearance from the fireplace opening, which forces a higher mantel position and adds a fire-hazard risk over time as wood warps and discolors. Non-combustible steel can be mounted directly above the firebox with zero clearance, meets all building codes, and is safe above both gas and wood fireplaces — giving you a cleaner look and a lower profile.
Is Mantel - Masonry & Prefab Fireplace Glass Doors | Custom non-combustible?
Yes. Every shelf is certified non-combustible and safe for direct fireplace mounting. Meets all US building codes for fireplace clearance.
What is the starting price?
Pricing starts at $2,265. Final price depends on length, depth, finish, and any add-ons (LED lights, brackets, banding) selected in the configurator.
