Buying Guide
- Glass thickness compatibility: Most locks target 0.15″-0.3″ (4-8 mm). Confirm your display case thickness before purchasing.
- Installation method: No-drill or stick-on solutions are easiest for temporary or rental setups. For permanent fixtures, drill-ready or mounting-pad options may provide stronger security.
- Keying strategy: Choose keyed-alike when you want to manage multiple cases with a single key; consider separate keys for high-value displays to limit access.
- Material quality: Zinc alloy cores and chrome finishes offer corrosion resistance and durability in daily display use.
- Security vs. convenience: A robust lock improves security but may require professional installation or more time to swap keys across units. Balance with your display frequency and access needs.
