Buying Guide: Key Purchase Considerations
- Security level: Four-digit locks offer a larger combination space than three-digit models, reducing the risk of unauthorized access. Look for hardened steel shackles and robust bodies for higher resistance to tampering.
- Weatherproofing: If lockers are exposed to the elements, choose weatherproof or rust-resistant finishes to maintain performance over time.
- Ease of use: Side window designs and one-handed entry features can speed up access in tight or crowded spaces, such as gyms or school hallways.
- Durability: For outdoor or high-traffic settings, prioritize metal bodies and corrosion-resistant materials over cheap plastic components.
- Compatibility: Confirm door backset, cross bore, and locker thickness to ensure the lock fits your specific cabinet or locker.
- Resetability: Fixed presets are common, but some models allow easy code changes. Consider whether you prefer a lock with a quick-change tool for code updates.
- Bulk needs: If you manage many lockers, consider packages or packs (like Puroma options) to simplify procurement and ensure consistent performance across locations.
