Our Advantages

Sliding glass doors are becoming more and more popular, because of the view and natural lighting that they provide. But there can be some difficulty when it comes to maintaine them, such as the rollers have worn out. The key part is knowing which roller matches the original. Many people believe that alternatives can be found by identifying the door manufacturer individually. Actually, Most rollers are generic and used by various door manufacturers.

As the professional manufacturer of sliding rollers, we use various identifying characteristics to determine the best replacement option for your door. In addition to the number of wheels your roller uses to support the door, the presence of dimples, bumps, cut-outs and flared edges on the rollers housing will narrow down replacement options substantially. The way that the assembly installs in the door frame is also vital. The key dimensions to confirm a replacement include the width and height of the roller’s outer housing, as well as the diameter of the wheel. In addition to the diameter of the wheels, the material that they’re made of, steel or nylon, is also a factor. Long-term, metal wheels are known to hold up better but they can also cause the track to wear out faster, especially on heavy doors. Nylon wheels tend to be kinder to the track but may not last as long as their steel counterparts.
