18" x 3/8" Liberty Hidden Countertop Support Plate, Gloss Black Finish

Liberty Hidden Countertop Plate For Floating Counters

Liberty Hidden Countertop Plate is a flat plate shaped bracket designed to hold countertop overhangs on a knee wall, so you can create a floating counter appearance on workstations and bar tops without visible supports in the way. The 18 inch x 3/8 inch plate size focuses support directly under the overhang, helping distribute weight along the wall instead of relying only on front cabinetry or corbels. Each hidden countertop support can hold up to 375 pounds when installed per installation guidelines, giving you capacity for thick granite, quartz, marble, other natural stones and concrete countertops in busy kitchen or commercial locations. The bracket is part of the Federal Brace Liberty series of workstation and countertop brackets, so it fits into projects where clean lines and open leg space are a priority. Finished in gloss black, it visually disappears under darker tops while still providing structural reinforcement along the knee wall.

Key Liberty Hidden Countertop Plate Details

• The flat plate shaped bracket design spreads support across the knee wall, which helps reduce point loading at the front edge of heavy countertop overhangs during everyday use.
• Mounting to a knee wall creates the floating counter appearance, keeping support under the surface so stools, chairs, and traffic paths remain clear for comfortable seating and movement.
• Each hidden countertop support holding up to 375 pounds provides capacity for thick stone or concrete tops, which matters when planning extended overhangs for dining or workstation areas.
• The 18 inch length with 3/8 inch thickness gives a low-profile support footprint, so you can route into the knee wall and still maintain a flush surface ready for countertop installation.
• Finished in gloss black, the plate blends with dark surfaces or shadows under the counter, helping the structural support stay visually unobtrusive in finished spaces.
• Placement within the Federal Brace Liberty hidden countertop plate line links this part to a family of sizes, which simplifies specifying matching supports across different overhang spans on the same project.

Countertop Support Plate Mounting And Routing Use

The Liberty Hidden Countertop Plate is designed to be mounted to a knee wall, so routing the top of the knee wall creates a flush mount hidden bracket location that aligns cleanly with the underside of the countertop. This routed installation keeps the 3/8 inch thick plate recessed, allowing plenty of chair and leg room under bar-height or counter-height overhangs because there is no protruding brace below. An additional 4 inch length beyond the selected 18 inch size is provided to account for mounting into the stud, which means a portion of the plate extends back into framing for a stronger mechanical connection. With this mounting approach, loads from granite, quartz, marble, other natural stones and concrete countertops are transferred back into the knee wall structure, supporting daily use at the overhang edge.

Where This Federal Brace Countertop Plate Works

Hidden Knee Wall Support For Stone Overhangs

The Federal Brace Liberty Hidden Countertop Plate is part of a workstation and countertop bracket class, so it is intended specifically for supporting countertop overhangs where appearance and usable space both matter. Mounted on a knee wall, the 18 inch plate runs directly under the overhang, allowing you to support heavy granite, quartz, marble, other natural stones and concrete tops in kitchens, reception areas, or office work counters. Because each hidden countertop support can hold up to 375 pounds when installed per installation guidelines, it suits situations where multiple users lean, work, or place equipment on the overhang edge. Routing the plate into the knee wall top keeps the surface flush, so the countertop can sit evenly across the support and framing without telegraphing bracket edges or steps.

Support Details That Improve Workflow And Finish

The Liberty Hidden Countertop Plate uses a flat plate shaped bracket profile, which simplifies layout and routing because you are working with a consistent 18 inch length and 3/8 inch thickness along the support path. That predictable shape allows straightforward measuring and marking before cutting the recess, saving layout time across multiple supports on a long counter run. The design provides an additional 4 inch length on top of the selected 18 inch size, so the plate reaches back into a stud bay for a secure connection, reducing movement at the overhang edge during long-term use. Finished in gloss black, the plate visually recedes into the shadow line under darker countertops, helping the installation present as a true floating counter while still delivering structural reinforcement. As part of the Liberty Hidden Countertop Plate line, this size can be combined with other lengths from 8 inches up to 20 inches, allowing you to match support lengths to varied overhang depths on the same project while maintaining the same installation approach and appearance.
