Buying Guide: Key Purchase Considerations
- Glass thickness compatibility: Verify the lock’s stated glass thickness range and inner diameter to ensure a secure fit for your display case doors.
- Keying and security: Consider keyed-alike sets for multi-door displays to simplify access control, or opt for different keys if you need compartmentalized security.
- Material and finish: Chrome zinc alloy is common and durable; stainless steel offers higher corrosion resistance in humid or high-use environments.
- Installation effort: Tool-free or screwdriver-assisted installs save time, especially in retrofits or larger displays.
- Durability in use: For high-traffic environments, prioritize anti-corrosion alloys and robust locking mechanisms to minimize maintenance.
- Aesthetics and size: Ensure the lock’s profile and finish align with the display’s design and do not protrude excessively or obstruct glass panels.
- Spare parts and keys: Check whether the pack includes multiple keys and whether replacement parts are readily available from the manufacturer.
