Frequently asked questions

How do I determine the correct torsion spring replacement?

You will need to determine 3 measurements: wire gauge, inner diameter, and coil-to-coil length. To figure out the wire gauge, measure 20 coils and refer to our size guide on the product page. Inner diameter is typically 1-3/4", 2" or 2-5/8". This is the diameter of the inside of the spring coil, not including the width of the coils. Finally, coil to coil length is the distance from the first spring coil to the last spring coil, not including the spring cones.



What is the difference between your garage door rollers?

All of our rollers have nylon wheels but the difference lies in the bearing and bearing protection. The highest rated roller that we have is the 6200ZZ bearing roller which has a door open / close cycle life of greater than 120,000 cycles at a 100 pound load. The 6200ZZ bearing has 8 ball bearings with a dual-cage assembly that dramatically improves the strength of the bearing and holds the balls in place while the roller wheel spins. The 6200Z bearing has a single cage assembly, which reduces the rating of the roller to 100,000 cycles over the lifetime of the roller. Even though our other rollers have 13-ball bearings, these rollers are rated at 10,000 door cycles as these bearings are loose inside the bearing assembly. The sealed 13-ball bearing has a plastic cap over the 13-ball bearing to protect from dust, dirt, and grime.
