When replacing and existing closer you want to make sure your new model matches the old. The big problem is that the closer body will not indicated your old model number. It may have some casting numbers or other indicators on the body, but they have nothing to do with the model number.
The reason these casting numbers are of no use is that a casting company will make ''blanks'' for many different companies. After the unit is cast, it is machined to the specifications of each manufacturer. You are best off to ignore these casting numbers completely.
You will want to pay attention to the bolt hole alignment used to mount the closer. Very few models use the same bolt hole pattern and this is the key to success.
In the case of the DC3210, the mounting pattern is for the Quick Mount bracket. If you need to replace a DC3210, you don't even need to remove the old bracket. Just remove the old closer body and replace it with the new.
Note that the DC6210 uses the same mounting bracket. Use a DC6210 is high traffic applications and the DC3210 in low to medium traffic areas. It is fine to mix the two models within the same building.
Model DC3210 is the only model produced under the DC3000 Series.
It is designed to be a Universal Closer, meaning it will work for most every door in your building. The spring inside the DC3210 is full adjustable sizes 2-6. This means it fits all door sizes up to a 48'' wide door. If you have an extra high door or extra heavy door you'll need to contact us to determine overall weight.
The adjustable spring means you can set the opening force to meet ADA requirements (Americans with Disabilities Act). For interior doors, 5 lbs. is maximum opening force allowed. You can adjust the spring during installation so the door opens easily.
When you have an exterior door, the requirement changes to 8 lbs. maximum opening force. This is trickier since exterior doors are subject to changing weather conditions. It is best to adjust your door on a ''normal'' day.
