My parents have installed a door with the Guardian lock, which has been serving faultlessly for 12 years. Due to a latch, the door is easily slammed and the tight fit is achieved. It perfectly protects from cold and noise. A mortise bolt in the lock case is also very convenient, it helps to unlock the door with one hand. You do not have to get your keys each time. My parents are very glad. They choose only Guardian lock!
