Are standard hanging file frames compatible with fireproof cabinets?

Hanging file rails for fireproof cabinets are typically included with the cabinet or are available as optional accessories. The interior dimensions of fireproof drawers are slightly narrower than standard file cabinets due to insulating walls, so off-the-shelf universal hanging file frames may not fit. Confirm that the frame dimensions match the drawer interior before purchasing third-party hanging file accessories.
