The self-contained, self-topped C-File units come in 5 drawer units only. Each drawer is outfitted with a rear hood and a double hinged metal flap at the front to keep drawings in place. While C-Files aren't designed to interlock, provisions have been made to stack them. Each steel plan file drawer features seamless construction, metal card holder, and tracks smoothly on silent ball-bearing nylon rollers. Die-formed stops keep each drawer from pulling out completely. Colors: Desert Sage, Gray, Black or White. FREE SHIPPING on any 3 Mayline Items except Parallel Bars. FILES FOR DRAWINGS UP TO 36" X 48"
