56" - 84" Floating Cabinet Bracket defines this InnovaShelf set as an adjustable support system for floating cabinets spanning between a 56 inch minimum overall width and an 84 inch maximum overall width, so you can plan wide runs within that range confidently. The set is part of the Floating Shelves and Concealed Brackets class, so it keeps support hardware hidden while carrying the load of the cabinet. The manufacturer part number FCB-5684 identifies this specific size range and capacity, which simplifies ordering repeat jobs or matching to drawings. Classified under Shelf, Closet & Garage Organization, this bracket set supports storage cabinetry in those spaces. A stated 1000 lbs weight bearing capacity when installed into two or more studs provides the structural performance needed for heavy cabinet loads in shop, garage, or closet applications.
The floating cabinet bracket set is specified with a 56 inch to 84 inch working width, so layout starts by confirming the cabinet falls inside that range before positioning the rails. The system provides 1000 lbs weight bearing capacity when installed into two or more studs, so the installation pattern centers on tying the rails and bracket arms back into structural framing. Because FCB sets are adjustable within the specified span, rails and arms can be set to match the cabinet size, then fixed so the cabinet shell engages the concealed support. The use of installation screws in the set gives a defined fastener approach for securing the hardware to framing and cabinet structure during mounting.
This InnovaShelf floating cabinet bracket is listed under Shelf, Closet & Garage Organization, so it is suited to wall-mounted cabinets in those storage environments. The 56 inch to 84 inch overall width range targets wider cabinets or grouped runs that fit this span, which is common in garage uppers and longer closet sections. Because the bracket is compatible with hardwood, plywood, MDF, and particle-board cabinets, it works across different construction levels, from solid wood shop cabinets to laminated panel boxes, which helps standardize hanging hardware across a job. As part of Floating Shelves and Concealed Brackets, the system keeps the structural elements hidden behind or within the cabinet, supporting a clean floating appearance while still providing structural support for everyday stored items.
Each FCB set contains a center brace that ties the system together, helping distribute cabinet loads across the span for more even support. Two rails in the set create a continuous mounting backbone, so loads transfer along the wall into two or more studs for the stated 1000 lbs weight bearing capacity when installed to framing. Two bracket arms connect the rails to the cabinet, which creates a rigid linkage between the wall structure and the cabinet shell for better alignment over the full 56 to 84 inch range. The adjustable nature of the FCB sets within that specified width supports repeatable layouts on different cabinet sizes without changing the basic hardware configuration. Installation screws in the set establish the fastening method for securing the center brace, rails, and arms, which helps maintain consistent installation practice from one cabinet to the next.
The 56" - 84" Floating Cabinet Bracket works in any size cabinet between the listed minimum overall width and maximum overall width, so cabinets must fall within that 56 to 84 inch span.
The floating cabinet bracket has a 1000 lbs weight bearing capacity when installed into two or more studs, supporting heavy cabinet contents in typical storage applications.
The bracket set is compatible with hardwood, plywood, MDF, and particle-board cabinets, allowing use across different case construction methods on the same project.
The FCB-5684 set uses a center brace, two rails, two bracket arms, and installation screws to create the concealed support structure behind the floating cabinet.
The FCB set can be assembled in shop or on jobsite, giving flexibility to prebuild support assemblies or integrate them during installation.
