There are 3 degrees of door locks. It is a system of good, better, better rankings. 1st grade is better, grade 2 and grade 3 is better is good. The
classification system was designed by the Builders Equipment
Manufacturers Association (BHMA), which is accredited by the American
National Standards Institute (ANSI standard). You will see the ANSI / BHMA written classification system. The score is gradual, which means you progress to grade 3 to 2 to 1 requirements and improve standards.
For grade 1 locks, some rules are as follows:
Lock latches (lever and button) extend door ¾ inch
Lock latches extend at least 1 inch from the door
These locks can support at least 10-75 lb.-ft. Beats Locking
They are tested to withstand at least one million opening and closing cycles
ANSI / BHMA standards are more involved and detailed, including things like finishes. These rules extend not only blocks entry, but also to privacy, passage and locks the store. All have a set of different standards depending on the type of lock. For a lock has a grade 1 rating will be built with quality quality materials. Manufacturing tolerances are also much more stringent. All this will come at a higher cost.
1 locks are used in commercial and industrial applications such as
offices, schools, hospitals, shopping centers and government facilities.
2nd grade locks are used in commercial and residential applications
and quality heavy locks 3 they are mainly used in residential
Any quality locking lock is not only itself but also strike, bolt, bolts, screws and other materials. How to install the lock is very important and will keep your note. For
example, if you take a lock that is a grade 1 and installed in a hollow
core door or with half-inch screws to hit this will lower the note. Any quality lock should be installed with the hardware that comes with it.
In general, grade 1 locks will be installed by locksmiths employed by large companies or locksmiths engaged. For all others like a small business or home, I recommend at least a 2nd year for all exterior doors. If the difference in cost is affordable to go with a note 1.
As I said in many of the articles I am writing to you, ask yourself: what am I trying to protect and how does that or value me?
