York Lock & Key Company

Locksets

We carry locks of all types for all applications. Our selection includes many lock
functions not typically found in other stores. If you have an unusual situation which
needs to be secured, give us a call. Additionally, we can do this in just about any
finish the job requires. Some of the newest and highly demanded locks are the
heavy-duty lever locks with the clutch mechanism. The clutch disengages the outside
lever from the latch mechanism rather than locking the lever rigidly. In a burglary attempt,
the rigid lever can be forced open by a determined thief by forcing the lever to turn.
The alternative allows the lever to turn but will not open the door because the clutch
disconnects the lever from the lock.


Lockset Grades

Here is ashort summary of lockset hardware grades. These grades require
that a lock meet all the minimum requirements listed. However, a lock may
excede some of these requirments, yet be rated lower due to a characteristic
which is not important to you. This is one reason why a professional
locksmith should be consulted addressing a security situation.

Fire rating is the toughest of all ratings. Hardware in this category
are labeled A for 3 hour doors, B for 90 minute doors, and C for
20 minute doors. They all must withstand a static holding force of
2000 pounds. They must also have a 500,000 cycle life. The
unit must be made of a single, non-plated, non-corrosive material.

Grade 1 hardware must hold a static force of 1000 pounds and have
a cycle life of 500,000. The unit must be made of a single,
non-plated, non-corrosive material.

Grade 2 hardware must hold a static force of 500 pounds and have
a cycle life of 300,000. The unit can be made of plated materials.

Grade 3 hardware must hold a static force of 300 pounds and
have a cycle life of 100,000.
