Norton 8500 Series Closer[/caption]
Quality Door and Hardware carries Norton Door Closers. Door Closers by Norton allow you to choose the specification needed to manage the traffic of the door. Before installation, a point to consider is the amount of traffic expected. 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 between 300-400 times a day and can last for three to seven years before replacement. Grade 2 closers are designed for medium traffic in a commercial application. These types of closers need a minimum of two valves to control the speed of the door. The first valve controls is called the sweep. When adjusting a closer, the ideal target time needed for the door to close is about six seconds. For exterior applications we recommend a closer with a back-check feature.

Door Closers are labeled as to how much traffic they are designed to endure before needing replacement. 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 reduced speed.
