Aluminum Brackets

Aluminum Counter & Support Bracket

RPC Aluminum Counter Support Brackets provide strong, unobtrusive support for counter tops, work surfaces, and heavy-duty wall-mounted shelving. Available in several sizes and finishes, the brackets support a wide variety of surface types and sizes. Use of counter support brackets reduces installation costs and greatly strengthens installation of custom vanities and counter tops.

RPC Aluminum Counter Support Brackets are designed for maximum strength and installation. When attached to wall framing in accordance with manufacturer’s recommendations each bracket is capable of supporting up to 450 lbs (204 kg). With proper coordination of vertical framing member locations, additional in-wall blocking may be avoided, and the brackets are easily surface-mounted following installation of wall finishes.

Bracket Installation

Install Aluminum Counter Support Brackets in accordance with RPC recommendations.

Fasten brackets securely to adequately-sized wall framing through wall finish using a minimum of 2 x 1/4 in. (51 x 6.4 mm) pan head screws with thread appropriate to either metal or wood studs. Install screws in each pre-drilled hole in the vertical leg of he bracket. “Toeing” crews where single wood studs are used is recommended to achieve adequate screw penetration.

Select sizes and type of screws for securing counter top to bracket as recommended by counter top supplier.
