This Sandusky Lee 800 Series lateral file cabinet is made of steel and has four full suspension file drawers for storing and accessing letter-size or legal-size hanging files. Full drawer extension on genuine progressive telescoping ball-bearing slides provides smooth, trouble-free operation. Built-in drawer interlock system prevents more than one drawer from opening at a time, reducing the chance of cabinet tip over. Center lock securely locks both sides of each drawer for positive security, two keys provided.
