Drums are 12" diameter spiral x 1-1/2" wide, 16-gauge, zinc-coated steel with grease-filled ball bearings mounted in the center of the drum to promote smooth operation. Springs are helical torsion, oil tempered, and coated to halt corrosion and increase life. Axle, drums, and springs are enclosed in a 26-gauge galvanized spiral tube to provide even curtain support.
Curtain

Step 1: Measure Framed Opening

Measure your framed opening. Doors are custom made to 1″ increments in both width and height.

FOR EXAMPLE: If your framed opening is 7’6″ wide and 8’0″ high, you would order a 7’6″W x 8’0″H (width first, height second) door. A = Width B = Height

 
 

Step 2: Measure Mounting Surfaces

Measure the mounting surface areas. NOTE: all mounting surfaces must be flush.

Step 3: Measure Door Clearance

Measure the door clearance. NOTE: Insulated doors require an additional 1″ of back room and head room.

Step 4: Select Door Model

Choose Model 944, 944WL, 955, 955WL, 988, or 988WL from the Door Model Selection Chart. If you are unsure of the best choice for your particular application, consider how your door will be used. The Model 944 is ideal for residential and light-duty needs. The Model 955 has heavier springs, brackets, bearings, drums, and guides, while the Model 988 offers the largest door dimensions. The “WL” models may be needed when building codes require a specific PSF rating.

Step 5: Order Your Door

Once you have completed the four preliminary steps for determining your needs, you are ready to order your door. *Trac-Rite strongly suggests contacting your local building inspector before placing an online order. The inspector will be aware of any wind load requirements for your area. Should you require certain wind loads, please contact Trac-Rite at 1-800-448-8979 to place your door order. Our Website is not able to accommodate specific wind load requirements.
