Legal documents are larger, heavier and more sensitive than letter paper, so the best file cabinet for legal documents states legal-size fit in its listing and locks. A cabinet that only fits letter folders will crease legal pages, and unlocked drawers invite trouble with confidential files. We compared five cabinets by stated size fit, drawers, locks, build and warranty, using only what each listing publishes.

How to choose the best file cabinet for legal documents
Legal-size fit is not always stated
The Aobabo and AFAIF state legal-size folders in the bullets; the Staples 4-drawer and 2-drawer claim legal only in the title while the bullets say letter size. If you file legal folders, pick a cabinet that states it in the bullets, not just the title; the Storex states letter or legal documents in its bullets too.
Locks and anti-tip
All five are lockable with key locks. The Aobabo and AFAIF add an interlock that opens one drawer at a time, and the Aobabo includes wall attachment hardware. For more locking options, see our best file cabinet with lock picks.
Capacity and weight
The AFAIF claims 55 lbs per drawer in the bullets against a 50-pound maximum in the spec table; the Aobabo states 150 pounds total. Heavier cabinets need a firm floor: the AFAIF weighs 62.4 pounds empty, the Aobabo 56.5 and the Staples 4-drawer 50.7. If you file dense legal archives, capacity per drawer matters more than drawer count.
Warranty and build
Only the Staples 2-drawer (7-year) and the Storex (90-day limited) state warranty terms. The metal builds of the Aobabo, AFAIF and Staples 4-drawer suit daily office use; the plastic Storex suits light home use. See our best file cabinet for home roundup.
Setup Notes
- Check the footprint: the Aobabo is 17.7 by 15 inches at 52 inches tall; the AFAIF is 17.72 by 15 inches at 50.12 inches.
- Assembly: the AFAIF and Aobabo need assembly with included hardware; the Storex ships fully assembled.
- Anchor the Aobabo with the included wall hardware; use the leveling feet on uneven floors.
- Confirm legal-size hanging folders fit: only the Aobabo and AFAIF state it in the bullets.
