One thing...a free standing lateral file cabinet has a burning desire to
tip. Especially when the top drawer is extended. It *will* tip if both
drawers are extended. There are various way to fix it one being a cleat
fastened to the floor or wall which retains one on the cabinet.


SFWIW, have several commercial metal lateral files.

They all are two high units and have an interlock that only allows one
drawer at a time to be open.
