Buying Guide
- Grade and certification: Prioritize Grade 1 locks for maximum security, especially on exterior doors and high-traffic entrances.
- Door compatibility: Check backset (2-3/8″ or 2-3/4″), door thickness, and bore hole spacing to ensure a proper fit.
- Lock type: Deadbolts provide strong resistance to forced entry; mortise locks offer integrated security with a high life cycle; lever handles balance accessibility with security depending on the environment.
- Material and finish: Choose corrosion-resistant metals (steel, brass) with durable finishes (satin, bronze) for longevity in varying weather conditions.
- Installation: Some models are easy DIY installs with common screws and a screwdriver; others may require professional installation especially for mortise locks.
- Keying and access control: Decide if keyed entry suffices or if privacy features (inside turn button, dual locking) are needed for emergencies and quick egress.
- Fire rating and safety: For interior/exterior doors, consider models with fire ratings to meet building safety requirements.
- Maintenance: Opt for locks with robust cylinders and anti-saw or anti-pick features for longer-lasting security.
These options provide multiple security approaches—from straightforward deadbolts to robust mortise systems—so you can select a Grade 1 solution that aligns with your door type, traffic, and safety needs without compromising ease of use or installation.
