Concealed storage floating shelf bracket from Federal Brace provides a discreet way to build hidden storage into a floating shelf or similar structure. The bracket is sized at 5.5 inches by 7.38 inches by 1.5 inches, so it forms a compact support that fits easily behind a fabricated cover box in tight wall or cabinet spaces. The black finish gives the bracket a low-visibility look, helping it blend behind the shelf structure so the focus stays on the finished piece, not the support. Once installed and concealed, the bracket acts as a storage tray, which lets you keep small valuables or essential self-defense items close without leaving them exposed. The design supports a concealed storage space of 6.8 inches by 5.25 inches by 1.25 inches, creating a defined cavity that is large enough for small items while still disappearing into the overall build.
This Federal Brace concealed storage bracket uses four 1/4 inch diameter mounting holes, so the layout directs you to a four-point fastening pattern that keeps the tray-style bracket tight to the mounting surface. The bracket relies on four 5/16 hex lag screws as the fastener specification, which pairs the holes with heavy-duty lag mounting to secure the bracket where studs or solid material are available. With its 5.5 inch by 7.38 inch by 1.5 inch size, the bracket can be positioned so the 6.8 inch by 5.25 inch by 1.25 inch concealed storage space aligns behind trim, a floating shelf, or a fabricated box, allowing you to coordinate the mounting location with surrounding finishes. The 0.25 inch thickness helps the bracket resist flex during installation and use, maintaining alignment so your fabricated cover opens and closes consistently.
The Federal Brace FB-10504 concealed storage floating shelf bracket is designed to act as both a structural support and a hidden tray. Its 5.5 inch by 7.38 inch by 1.5 inch profile fits behind a fabricated box or shelf face, so you can integrate it into shelving, cabinets, or similar wall installations without changing the external look. The 6.8 inch by 5.25 inch by 1.25 inch concealed storage space defines a shallow compartment that can sit behind a false bottom or back, allowing storage for compact valuables or essential self-defense items. Because the bracket finish is black, it visually recedes behind wood, laminate, or painted components, supporting installations where a viewer sees only the finished surface while the steel tray and mounting remain hidden. The 50 lb carry capacity means the bracket can support the combined weight of the custom box or shelf components and appropriately sized contents, giving flexibility for different room types and storage concepts.
The defined concealed storage space of 6.8 inches by 5.25 inches by 1.25 inches gives precise interior dimensions, which simplifies designing a matching cover box or shelf cavity that opens cleanly without interfering with the bracket. The 0.25 inch thick bracket body adds rigidity, so the tray maintains its shape under load, helping lids, false panels, or sliding covers stay aligned over time. With four 1/4 inch diameter holes and a specified 5/16 hex lag screw fastener, the bracket encourages a consistent mounting method that locks the steel to framing or solid backing, reducing movement that could otherwise affect how tightly a concealed panel seats. The 50 lb carry capacity rating provides a clear performance target, which supports repeatable builds where the same bracket can be used across multiple locations with predictable load behavior. Combined with the black finish, which keeps the support visually unobtrusive in shadowed cavities, these details work together to help installers and serious DIY users create concealed storage solutions that behave the same way from project to project.
