What Are Extended Mantel Kits and How Are They Used?

Extended mantel kits are innovative solutions for creating extra-wide, non-combustible fireplace mantels, typically ranging from 7 to 10 feet long. Designed to accommodate oversized fireplaces and grand feature walls, these kits allow you to achieve the look of a continuous timber beam with modular components, without the weight, clearance issues, or safety concerns of real wood. Our Extended mantel kits are especially popular for those wishing to combine an upper beam mantel with a lower floating hearth beam to complement today’s linear fireplaces

Each kit includes:

• A core mantel beam (e.g., 60" or 72")

• One or two 24" extension pieces for length customization

• Matching decorative brackets

• Mounting hardware and a touch-up kit

Crafted from Burncrete™, our proprietary, fire-rated concrete composite, these mantels are ASTM E136 certified and safe for installation above gas, wood-burning, or electric fireplaces.

Why Use Decorative Brackets?

The included decorative brackets serve both aesthetic and strategic purposes:

• Visually break up long spans to prevent the beam from looking artificial or overly uniform

• Disguise extension seams, maintaining the illusion of a single, continuous reclaimed beam

• Add a rustic or industrial accent, reinforcing design themes like farmhouse, lodge, Cabin, or Loft-industrial

• Offer visual weight and balance—especially important when centering artwork, mirrors, or a TV above the mantel

Though not structural, these brackets create a strong visual impact while enhancing the overall authenticity and realism of the extended mantel design.

Perfect For:

• Large stone or brick fireplace walls

• Longer and narrower Linear Fireplaces

• Fireplace Mantel and Floating Hearth Configurations

• Vaulted ceilings or open-concept great rooms

• Designers looking to scale proportionally to oversized architectural features

• Homeowners wanting a dramatic fireplace upgrade without custom carpentry

With easy-to-install hardware and optional beam sizes, our extended mantel kits make it simple to elevate your space with the timeless look of reclaimed wood—safely and affordably.
