British Standard BS3621 Sash Locks
British Standard BS3621 Sash Locks are ideal for front doors (and back doors of course), as they have a latch part operated by handle, and then a tough deadbolt locked and unlocked by key. Insurance companies typically require BS3621 locks these days, so it's a good idea to make sure you comply by fitting a lock with this British Standard kitemark.
We offer a wide range of sizes and finishes, as well as keyed alike BS3621 locks, allowing all your doors to operate from the same keys should you want them to; very handy for those who don't want to end up with a bunch of keys weighing them down!
