How do I prevent flat-file drawers from binding?

Flat-file drawer binding is usually caused by overloading (exceeding the drawer weight rating), misalignment of the cabinet on an uneven floor, or accumulated debris on the drawer slides. To fix: first empty the drawer and test; level the cabinet with adjustable leveling glides; clean and lubricate the ball-bearing suspension slides with silicone spray. Do not use petroleum-based lubricants — they attract dust. At OfficeFurniture2go.com, all our commercial flat-file cabinets use precision ball-bearing slides — call 1-800-460-0858.
