Abstract

A hanging file support frame has a pair of file folder support rails and a pair of transverse members. Four corner fittings supported in an elevated position each have a substantially vertical slot receiving one end of a rail and a substantially horizontal slot receiving one end of a transverse member. Each transverse member overlies both rails to prevent the upward movement of the rails.
