Consider these five factors:
1. Panel thickness — measure the door/drawer panel; the lock housing length must match it.
2. Door type — swing door, sliding door, or drawer; each requires a different lock mechanism.
3. Security levelmedium (keyed, anti-pry) or high (combination/electronic).
4. Usage frequency — high-traffic cabinets (offices, schools) need wear-resistant, all-metal internals.
5. Keying requirement — do you need keyed-alike, keyed-different, or master-key systems?
