15" - 21" Floating Cabinet Bracket from InnovaShelf is an adjustable FCB set that works in any size cabinet between the listed minimum overall width and maximum overall width, so one kit covers a range of cabinet sizes on the same job. This floating cabinet bracket is part of a system in the Floating Shelves and Concealed Brackets product class, so it supports clean, concealed wall-mounted cabinet designs where visible supports are not desired. The manufacturer part number FCB-1521 clearly identifies this specific width range and performance level for reordering or matching project specs. The FCB set design focuses on hanging a floating cabinet securely while keeping components concealed, which helps maintain a streamlined look across shelf, closet, and garage organization layouts that call for floating cabinets.
The FCB floating cabinet bracket has a listed weight bearing capacity of 500 lbs when installed into two or more studs, which directly ties performance to stud-mounted installation and supports heavier cabinet loads within that condition. The web description notes that the bracket is compatible with hardwood, plywood, MDF, and particle-board cabinets, so the same system can be used across different cabinet box materials in a shop or onsite setting. The description also states that the FCB set can be assembled in the shop or on the jobsite, which gives flexibility in workflow and allows fabrication teams to choose where to build the cabinet and support assembly.
This 15" - 21" Floating Cabinet Bracket is described as an FCB set that works in any size cabinet between the listed minimum overall width and maximum overall width, so it is intended for cabinets falling within that span in shelf, closet, and garage organization layouts. The product sits in the Floating Shelves and Concealed Brackets class, which means the support is designed to be concealed inside or behind the cabinet structure while the cabinet appears to float. That concealed approach matters when a project calls for wall-mounted cabinets that visually align with floating shelves, since it helps keep the front and underside of the installation clear of visible support hardware. Because the product name and description identify it specifically as a floating cabinet bracket, it is focused on cabinet applications rather than open shelves, so it pairs logically with enclosed storage runs in closets or garages that still use a floating look.
The web description specifies a 500 lbs weight bearing capacity if the FCB floating cabinet bracket is installed into two or more studs, tying its rated capacity directly to a stud-based mounting method. That condition means the bracket is intended to transfer cabinet loads back to structural framing through its center brace, two rails, and two bracket arms, creating a defined load path when cabinets are hung. The description notes that the set is compatible with hardwood, plywood, MDF, and particle-board cabinets, so builders using different core materials can work within the same concealed bracket system while keeping the load rating tied to stud mounting. It also states that the FCB set can be assembled in the shop or on the jobsite, which supports consistent results across production-style cabinet runs or one-off installations by using the same core components and layout approach. Together, these details frame the bracket as a repeatable method for hanging floating cabinets where loads, materials, and location are all defined up front.
