Difference Between Slam Lock and Dead Lock Security Gates
Traditional Trellidor sliding security gates are fitted with either a deadlock or a slamlock, depending on the model and customer preference.
THE DIFFERENCE BETWEEN THEM IS:
- Deadlock – A sliding security gate fitted with a dead lock gate requires a key to lock it when the trellis gate is closed. These locks were invented by Jeremiah Chubb in England in the 1800's. The Chubb company is known for its safes and locks. Well-made dead locks are usually strong and robust when attacked.
- Slamlock – A sliding security gate fitted with a slam lock gate automatically locks when you slam the trellis gate shut. The concept originated with the Yale lock, invented in the late 1800's in America. It is a convenient locking system but is not always the strongest type of burglar gate lock when attacked.
Both lock types engage several locking points within the lock stile for added security and strength under attack. Our computer-cut keys add another layer of protection. Each key has a unique code to help prevent unauthorised duplication of keys.
