Fireplace Mantel Bracket
Polure fireplace mantel brackets bring timeless architectural support and ornamental framing to electric fireplace mantels, shelf displays, and wall surrounds. Precision-molded from rigid high-density polyurethane (150-220 kg/m³), these brackets provide high impact strength and wood-like durability without creating heavy loads on wall framing. Featuring a closed-cell structure with less than 1% water absorption, they will not warp, swell, or cultivate mold in humid indoor areas. Thermally resilient between -100 °C / +80 °C and rated fire Class B2, each bracket arrives pre-treated with factory white acrylic primer. Installation requires a continuous bead of polyurethane assembly adhesive across back contact zones combined with countersunk mechanical screws (silicone is strictly forbidden). Fill screw holes with acrylic putty, sand smooth with 180-220 grit paper, and finish with two coats of interior paint.
