The “U” section shelving strip combines the strength of the Flat bookcase strip with the versatility of the raised section designs. At 14mm overall width, it is the narrowest of the four styles, and yet its 2mm material thickness makes it one of the strongest. The “U” channel shape allows it to be surface fitted, let in flush, or have tiles or décor panels butted up to it. A 6mm rebate or décor panel thickness would allow the strip to be fitted flush, but greater depths are not a problem as shelving studs are within the overall width of the strip. When using surface mounted “U” section bookcase strip, shelves must be a minimum of 12mm shorter overall than the internal width of the cabinet.
