Buying Guide
Key purchase considerations help buyers select the right lock for roll-up doors in commercial settings.
- Door compatibility: Confirm handle size, mounting method, and whether the lock fits standard or specialty doors (Todco, Wayne Dalton, etc.).
- Security level: Consider hidden shackle designs, anti-cut features, and drill resistance. Hidden shackles reduce exposed points for tampering.
- Keying option: Decide between keyed alike, keyed differently, or combination locks. Keyed differently improves access control for multiple users.
- Durability: Look for hardened steel, zinc alloy components, and weather-resistant finishes for outdoor use.
- Installation: Some models require mounting hardware and drilling; verify included hardware and whether professional installation is recommended.
- User access strategy: For sites with many workers, a combination lock or a widely shared keying approach can reduce key management complexity.
Practical buying questions
