Door Closers

We carry LCN, Norton and Cal-Royal door closers. All of these brands allow you to choose the specifications needed to manage the traffic of the door that you are controlling. For a new installation, a significant point to consider is the amount of anticipated traffic expected for the door. Closers are labeled as to how much traffic they are designed to endure before needing replacement. An important factor, when purchasing a closer, is to buy a sizable closer. This allows you the opportunity to adjust the power of the unit. This is also known as torque. When you increase the amount of power to control the door, it allows one to control the door with less speed.

Customer Reviews

5/5 stars

The phone help was great. There was no name/information on the door closer that I needed to replace but after just a few short minutes I had the replacement closer ordered. When it arrived, it not only fit the existing holes in the door, it was an exact match. I will definitely use Wholesale Locks again.

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 300-400 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 50-100 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. When adjusting a closer, the ideal target time needed for the door to close is about six seconds. The first part (sweep) will consume the majority of this time, about 4.5 to 5 seconds. This allows someone to let go of the door without having to be concerned about being struck by the door as it starts its closing cycle. Once it reaches the latch point, the speed can be increased, providing enough momentum and pressure needed to latch the locking mechanism on the door.

For exterior doors, a third valve or control is needed. This called the backcheck. The purpose of this valve is to slow the door down from opening too fast and/or hitting against a stop or wall. With this valve you can set the position of the opening where you want it to start cushioning the speed or momentum of the door, before it reaches the full degree of opening. Some Grade 2 closers do not come with a backcheck control.

If the door closer is installed to allow the door to open to 115 degrees, one might adjust the backcheck to start slowing the door down at approximately 85 degrees. For all exterior applications we highly recommend a closing device with a backcheck feature.

Warranties vary from each manufacturer. Available standard finishes of aluminum, duronodic (dark brown), and flat gold. Plated finishes are also available.
