Overall Size: 1829mm x 24mm Commonly called "Top Hat" section because of its raised centre section, this strip is specifically designed for surface fitting. The wide flanges also allow other fitting methods such as spot welding to be utilised, making the design suitable for installation within steel cabinets. When using surface mounted raised bookcase strip, shelves must be a minimum of 7mm shorter overall than the internal width of the cabinet. For matching studs see product codes 46285 or 46286. Supplied without fixing screws.
