How to Identify Doors by Model Number, Serial Number, and PID Numbers - DDM Garage Doors Blog

Posted July 28th, 2017 at 6:38 pm by Sales Team

If you have a garage door made by Clopay Building Products Company, Ideal Door Company, or Holmes Garage Door Company, you may be able to use the model number, PID number, or serial number to determine the door weight so you can select the proper replacement springs. Finding the label that contains these numbers may save time and energy that you would otherwise spend measuring the springs or weighing the door. However, these labels can be difficult to find. Here are some helpful tips.

A garage door has three dimensions: width, height, and thickness. Normally, you can find the model number on a label on the thickness part at one end of each section. At the factory or distribution center, when you stack doors they can easily be identified.

Clopay Doors

Most Clopay doors have labels placed on the inside of the door, usually at the left end of the bottom or first intermediate section. Sometimes the sticker is at the right end of the door. On this label, you will find the door serial number. Usually, the model number of the door is embedded in the serial number, but on newer doors, it is embedded in a separate PID number, as you see in this Model 4050 below.

Clopay began using this white sticker with the orange warning label in 2003, and the company still uses it. The serial number, designated as “S/N,” usually has 12 numbers with an additional letter. The PID number has 17 letters; it includes both the model number and the door size, here “8000800,” designating a door that is eight feet wide and eight feet high.

The yellow sticker shown below was used from about 1998 to 2003. The serial numbers during those years contained 16-18 digits. The model numbers are usually located in the middle of the serial number as you see here in this model 4050.

Before 1997 Clopay used blue stickers on their doors with 15-16 digits in the serial number as you see in this model 1000.

Over the years, Clopay has used a number of other stickers, such as this white label stuck to the top of an intermediate section.

It is possible to find identifying labels on flag brackets which support the vertical and horizontal tracks.

Ideal Doors

Ideal has used a variety of stickers over the years. As with most manufacturers, labels are stuck to one end of each section as we see here with the door partly open on this S/R 4RST door. If you are unable to open the door, look behind the lower vertical track with a flashlight on both sides of the door to find this label. It will list a 3-6 digit standalone model number.

Ideal also uses labels mounted on the inside face of the sections. It is similar to what is found on Clopay doors, as you can see on this model R6R4 garage door.

Many of the Ideal doors have long serial numbers just as Clopay has. Below you can see the model number RDP38 embedded in the serial number.

Newer Ideal doors have the longer serial numbers and PID numbers, as is visible on this model SRP-38 door. As with the Clopay doors, the serial number, designated as “S/N,” usually has 12 numbers with an additional letter. The PID number has 17 letters; it includes both the model number and the door size. For instance, here “160007,” designates a door that is 16′ feet wide and eight feet high.

Holmes Doors

Similar to Ideal Door, Holmes labels list a standalone model number. And like Ideal or Clopay, a Holmes label may be stuck to the flag bracket. You can also find them on one side of the reinforcing strut if there is one.

IMPORTANT: If you live in Florida or along the coast, you may have a wind-rated door, as you see above. The “W6” after the model 42 designates a wind code rating of six. Clopay, Ideal, and Holmes all use similar wind code designations, but their part numbers will be different.

Making Sense of a Long Part Number

If you find a long part number, if there is no PID number, and if you can’t identify the model number, look in the middle of the part number and check one of our pages where we offer springs by model, manufacturer and serial number. On our Standard Torsion Springs page, for example, you will click “Model Number” and then select the manufacturer. After that, click the draw down menu and find your model number in the list.

The model numbers in the list above have between two and four digits. Look for these digits in the middle of the long part number on your garage door. On rare exceptions, you will not be able to find the number on our list because some models were in production for only a short time. If you need help, please contact us.
