Invention #2. Mr. Johnson evidently wasnt thrilled with having to get out and open his new-fangled garage door. Five years after inventing the overhead door, he invented the first automatic garage door. We like this guy!
One of the much in demand locks is that of the exit control lock. It is mostly used for the back door. However, you need to follow some regulations if you use this lock. If you want it to be more durable, then you can opt for the one that has cast aluminum housing so that it can resist attacks as well as corrosion. Additionally, it is quite easy to install this door lock. It is battery powered, hence easy to use. The exit locks come in a wide variety. If you do not want to get confused, then opt for the one that has exit bar sign in English, French, German, Dutch, Italian, and Chinese. These locks are usually available with saw-resistant deadbolt along with alarm horn of high decibel, which helps to prevent burglary. There are also some exit locks that have outside key control in them.
Many people wonder how much they should trust a fire rated door. This is a difficult question. People shouldn't assume the door will keep out all smoke, and they should still follow safety protocol for exiting a building. Keep low, remain calm, and proceed in an orderly fashion toward an exit. Exit stairwells in buildings generally are considered the safest exit means because they are usually built behind fire rated walls and fire doors.
