Trac-Rite Door was formed in 1981 under the premise that we could build a better quality rolling door than could be purchased at that time.  It turned out we were right.  We began making lightweight rolling curtain doors and soon had a reputation for producing one of the best, if not the best curtain door available.  But as with all competitive business ventures, it is not enough to do something good once and be satisfied with our accomplishment.  So we continued to improve our doors and expand our product line with new and innovative designs, always keeping the idea of quality at the forefront.

How are the guides on Trac-rite's Service Door manufactured?
Trac-Rite's guides are always manufactured from three structural steel angles, minimum 3/16" thickness.  They are prime painted on all sides before they are assembled, so in case there is some field adjustment, there will be no exposed steel susceptible to rust.  These guides are also preassembled at the factory with carriage bolts, to further facilitate any field adjustments.

What does the standard bottom assembly include?
Trac-Rite's Service Door bottom assembly is always made up of two hot-dipped galvanized steel angles, minimum 1/8" thickness, with an adjustable rubber bottom seal inserted between them.  This bottom assembly is held together with stainless steel carriage bolts, which when loosened, will allow you to adjust the bottom seal up to 1/2" as needed for uneven concrete situations.

How is Trac-Rite's barrel assembly put together?
The Service Door barrel is made of a minimum 6-5/8" O.D. steel pipe and has tapped lugs welded 10" - 24" on center where the starter slats will be attached.  There are no barrel rings with our system.  The tension side uses screws to attach the pipe to the spring casting.  This casting houses a sealed ball bearing.  The springs are attached to these castings without the need for torches.  Each end of the spring has a looped end which fits through and hooks around the casting.  The spring is kept in place by a bolt and a pin, both of which keep it from popping out of the casting.  The bracket supporting the drive side of the axle shall be fitted with a greasable, sealed ball bearing in a cast iron housing.

What are the slat specification?
Trac-Rite's standard slats are made up of prime painted, G-90 galvanized steel, with galvanized slats available for a deduct.  This primed finish has a .2 mils epoxy base coat and a .7 mils gray polyester top coat applied on both sides of the slat.  Only galvanized, malleable cast iron end caps will be used.  No stamped steel end caps are available.

How does Trac-Rite determine windload?
When calculating the 20 pounds per square foot windload, Trac-Rite performs a deflection, stress and sheer analysis using the full safety factors normally accorded any standard engineered building design.

What are the advantages of Trac-Rite's insulated plastic backer?
Trac-Rite's PVC backer eliminates conduction loss of metal to metal contact that's present when a steel backer is used.  Trac-Rite's insulated door went through rigorous testing procedures.  From cycle testing in below freezing temperatures to deflecting the curtain with a forklift, the door incurred no damages and none of the plastic backers popped off!
