12" x 23-1/4" Harrison Hidden Countertop Support, Black Finish

Harrison Hidden Countertop Support For Floating Counters

Harrison hidden countertop support is an H-shaped flat top plate designed to mount on the top of a knee wall, so it creates a floating counter look while carrying the countertop overhang. The arms sit flush with the top of the half wall, which lets the overhang rest level across the support and keeps the bracket out of sight during use. This Harrison Top Plate model in size 23.25 x 12 x .25 uses arms of 10 inches on both sides to support up to 14 inches of overhang, giving you working space without adding visible corbels. The bracket uses a black powder coat finish, so the steel surface is protected while remaining visually discreet under typical dark tops. A 3.25 inch middle bar mounting plate area gives a defined fastening zone along the wall, helping layout and installation planning.

Key Harrison Top Plate Details For Projects

• The 23.25 x 12 x .25 inch overall plate size provides a broad bearing surface, which spreads countertop load along the top of the knee wall for stable support.
• Arms of 10 inches on both sides are rated to support up to 14 inches of overhang, so you can plan seating or work edges within that range around a half wall.
• The black powder coat finish covers the bracket surfaces, helping resist wear while keeping the support visually low-profile behind darker cabinetry and tops.
• The H-shaped flat top design mounts directly to the top of the wall, so the floating support arms sit flush and keep the underside of the counter cleaner and easier to work around.
• The middle bar mounting plate area of 3.25 inches centers the bracket on the wall, giving a clear strip for fastening along the structural member for consistent placement from bracket to bracket.

Hidden Countertop Support Mounting And Fit Details

The Harrison Top Plate Hidden Countertop Support is designed to mount to the top of a knee or half wall, so the bracket sits directly under the countertop line instead of on the side of the wall. The arms sit flush with the wall top, which lets the fabricator rest the substrate or countertop right over the support without shimming for bracket thickness. When installed per the installation guide, each bracket holds up to 375 lbs when installed touching side by side, so multiple brackets along a run can share heavy overhang loads. The countersunk holes in the bracket allow fasteners to sit below the plate surface, so the countertop can sit flat on the steel without rocking on screw heads.

Using Harrison Hidden Supports In Real Work

Where This Hidden Countertop Support Performs Best

The Harrison Hidden Countertop Support by Federal Brace is built for mounting on the top of a knee wall, so it fits applications where a half wall separates spaces and the countertop bridges both sides. It is designed to support overhang on both sides of a half wall, which works well when one side serves as extra eating space and the opposite side is used as a breakfast bar or open storage space. The floating support arms sit flush with the top of the half wall, so the overhang remains continuous from room to room without visible brackets interrupting legroom or storage. With arms of 10 inches on both sides supporting up to 14 inches of overhang, this bracket suits typical residential bar depths, allowing stools or work space on either side of the wall.

Details That Support Repeatable Overhang Results

The H-shaped flat top plate gives a consistent geometry for layout along a half wall, so installers can align multiple Harrison hidden countertop supports side by side and know each arm sits at the same elevation. When installed per the installation guide and placed touching side by side, each bracket holds up to 375 lbs, which helps distribute heavy stone or solid-surface loads along the run. The 3.25 inch middle bar mounting plate area offers a clear region to fasten through, simplifying repeated measurements across several brackets. Countersunk holes in the plate keep fastener heads below the steel surface, so the countertop rests directly on the bracket, improving contact and reducing potential high spots that could affect templating. The black powder coat finish keeps the steel darker under the counter, which helps the support visually disappear when viewed from below, keeping attention on the counter rather than the structure.
