Why You Should Bother With Commercial Door Closer

We know in our own house the value of a door closer. It provides reliable security and convenience for the members of the household because of the control one can avail out of a door closer. Now imagine if you run a business. Basically it entails that there are way more people coming in and out of the doors. Thus, there is a need for commercial door closers in every office building.

The typical definition of a door closer is that it is a mechanical device that closes a door, in general after someone opens it, or after it was automatically opened. Manual and automatic are two general styles of door closers.

There are two general categories of door closers offered by the market today:

Grade 1 closers are designed with multiple controls including sweep, latch and backcheck. Grade 1 closers are designed to endure high traffic areas and are typically used for main entrances of most businesses. These closers are generally used 300 to 400 times a day and last for three to seven years before needing replacement.

Grade 2 closers are designed for medium traffic in a commercial application. An example of this is an interior door in an office area that is used approximately 50 to 100 times a day. These types of closers would need a minimum of two valves to control the speed of the door. The first valve controls what is called the sweep. This is the point from where the door is fully open until it reaches about 10 degrees remaining to close. At the 10 degree point another valve takes over to control the final speed. This is called the latch speed.

Commercial door closer is also known as commercial door lock. There are certain types of commercial door locks and how to find the appropriate one for your needs.

Lever lock

The most common lever lock is known as a cylindrical lock. This lever lock is installed on the door using a 2 1/8 inch hole drilled through the door with a 1 inch hole from the edge of the door. It also uses two additional holes outside the perimeter of the 2 1/8 inch hole to stabilize the lock and prevented it from twisting on the door and causing a malfunction. The mounting post hole locations vary across the manufacturers.

When choosing a lever lock one needs to always take into consideration how often the door is going to be used. If the door is in a high traffic area than a grade 1 lock should be chosen for this application. On a door that is used about 500 to a 1000 times a day, a grade 1 lock should last about five to seven years without needing replacement.

Mortise lock

Mortise locks require that a pocket is cut out from the edge of the door allowing the mortise lock case to slide into the door pocket. On the face of the door smaller holes are cut for the lever handles, mounting posts and mortise cylinder. Most mortise locks are grade 1 and are the ideal application for high traffic areas. Mortise locks are used on most commercial office buildings. Mortise locks provide more choices for different types of trim.

Door knob locks

Commercial door knob locks fits into a 2 1/8 inch diameter hole and require a 1 inch hole from the edge of the door. These locks are still available but not used as often because ADA now requires a lever instead. Door knob locks are available in grade 1,2, and 3. These locks come in the standard functions. The most common functions are entry, storeroom, classroom, passage, and privacy.

Commercial deadbolt locks

Commercial deadbolt locks are heavier than most residential great locks. These locks are also graded to provide the consumer the ability to compare locked equally. Some deadbolts have the UL listings which may be required on some applications.

Experts of commercial door closers will help you find the right lock for your commercial application. They can also provide you the exact replacement lock you need or all the necessary information to choose an alternate lock to fit your application.
