Security Screen Door Locks
Security Screens for your home
There is no doubt that security screens have been one of the best additions to modern homes for people that live in a tropical environment. In Australia and many other warm countries it is essential to have good airflow through your home, keep the insects out and not let unwanted people in.
Two main types of security screen doors
The main types of security doors are swinging and sliding security screen doors. Both swinging doors and sliding doors are secured by a mortise lock that fits inside the channel of the door frame. They use a teardrop locking cylinder similar to what you would find on European doors. The cylinders are slightly different mechanically so the specific cylinder for a screen door mush be used.
Swinging Security Door
A swinging security screen door will have a lever handle on both sides of the door and a snib for locking when at home. The swinging door will lock with a straight bolt into the security door frame. The bolt on some models will extend further when the door is in the closed position for a deeper and more secure action.
Sliding Security Door
Sliding security screen doors usually do not have a lever handle and will have a low profile release handle on both sides of the door. Sliding security door locks require a low profile as they must be able to slide past the glass door. They lock into a strike which is fitted to the door frame. Most sliding door locks have an anti friction design. This requires them to be latched into the strike before they will lock.
Triple Lock door
Both sliding and swinging security screen locks can be fitted with a triple lock attachment. The triple lock kit adds top and bottom locking points to the door. This makes the door much harder to force open and adds another dimension to the security screen making it a true security door and not just a fly screen.
Lock Cylinder Types
There are a range of cylinders that can be fitted to security screen doors. They vary in quality from very ordinary to very secure. A locksmith can provide a cylinder on a high security keyway that will be almost impossible for a burglar to pick the lock. Sliding doors may require a low profile cylinder to avoid hitting the glass door when sliding. There are also a range of these low profile cylinders and they too are available in a range of security levels
Just about all security screen door locks can be keyed to the same key. If you have quite a few security doors this can be a great advantage. Security doors can also be changed to suit other keys such as the key for your front door. The ability to have the whole house on just one key can make life very simple.
