Which Lock Standards Actually Matter?
For securing our homes and businesses, the standards we choose matter considerably. These standards make sure our locks provide maximum protection and meet insurance requirements. We focus on specific certifications such as BS3621, TS007 3-Star, and SS312 Diamond to deliver the best security solutions.
BS3621-rated mortice deadlocks are essential for wood doors, acting as a robust back-up lock. For modern composite and UPVC doors, the TS007 3-Star Kitemark anti-snap euro cylinders are the gold standard, providing anti-snap, anti-bump, and anti-pick protection. Additionally, SS312 Diamond Sold Secure cylinders are often required for high-value properties, ensuring top-tier attack resistance.
Here's a quick breakdown:
| Standard | Application |
|---|---|
| BS3621 | Wood doors, insurer back-up lock |
| TS007 3-Star | Composite/UPVC, anti-snap |
| SS312 Diamond | High-value homes |
| BS EN 1303 | Commercial/key-control doors |
