Mantel Support Bracket
Polure mantel support brackets provide structural styling and refined decorative support for fireplace surrounds, electric mantel displays, and wall shelves. Molded from rigid high-density polyurethane (150-220 kg/m³), these brackets offer wood-like mechanical toughness and crisp detail without imposing structural stress. The closed-cell polymer structure ensures water absorption below 1%, making them suitable for damp environments without warping, rotting, or swelling. Thermally resilient between -100 °C / +80 °C with a Class B2 fire safety rating, each bracket comes pre-coated with factory white acrylic primer. Secure installation requires a continuous bead of polyurethane assembly adhesive across rear contact edges combined with countersunk mechanical screws (silicone is strictly forbidden). Fill screw holes with acrylic putty, sand smooth with 180-220 grit sandpaper, and coat with two layers of quality interior paint.
Frequently Asked Questions
Can the Mantel Support Bracket be used near real wood burning fireplaces?
The Mantel Support Bracket is suitable for electric or vapor fireplaces up to 80°C. Open flames and direct fire exposure are strictly forbidden.
What density material is used in the Mantel Support Bracket?
It is crafted from high-density rigid polyurethane ranging between 150 and 150-220 kg/m³ (production target ~160 kg/m³), giving it high impact resistance.
Is silicone adhesive suitable for installing the Mantel Support Bracket?
No, silicone is strictly forbidden. You must use polyurethane assembly adhesive combined with mechanical screws.
How is the Mantel Support Bracket finished?
After countersinking screws and filling holes with acrylic filler, sand lightly with 180-220 grit sandpaper and apply two coats of paint.
