Identifying the Right Replacement Roller for Your Patio Sliding Glass Door
Removing patio door rollers will require a friend’s help but it’s well worth the effort to identify the
correct replacement the first time around!
Sliding glass doors are a feature that many people look for or go out of their way to have installed.
It’s not hard to imagine why considering the view and natural lighting that they provide. Despite their
benefits, there can be a few bumps in the road when it comes to maintaining them. The number one
offender we encounter is when the rollers have worn out, turning the simple process of leaving and
entering the home into a chore.
Luckily, replacement rollers that are suitable for many types of patio doors can be found on SWISCO.com,
among other hardware such as tracks, track covers, handles and locks. The tricky part is knowing which
roller matches up to the originals. Many homeowners assume that a replacement can be located by
determining the door manufacturer alone. Unfortunately, that is not the case. Most rollers are generic
and are used by various door manufacturers. For this reason, it is vital to see the original roller
assembly fully removed from the door frame.
SWISCO’s experts 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. None of these
characteristics can be seen while the roller is installed, which is why the experts insist on seeing the
assembly fully removed before recommending a replacement for any patio door roller.
Once you have a clear image of the roller to submit to the
experts, dimensions are needed to ensure that the recommended part will fit snugly inside the
door frame. 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. Many people will ask why the material of the wheels matter at all? 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.
In some cases, a match may be available that doesn’t come with the same nylon or steel wheel as the one
you’re replacing. In that case, SWISCO’s selection of roller and axle
kits can often be used to replace the wheel on the new roller with one that is the same size and
material as the original.
PRO TIPS
A little known fact for most homeowners is that sliding glass door rollers have inner and outer
housings. It can be easy to remove what you think is the entire roller but the outer housing can be
left inside the door frame.
Disassembled Patio Glass Door Roller
It’s important to make sure that the entire assembly is removed to avoid having to remove the door a
second time.
If the new roller seems too high or low to reinstall the door properly, try using the adjustment
screw to alter the height of the wheel to create the proper amount of clearance.
If you wind up with a broken handle on the door, check the rollers and track for debris or damage to
prevent breaking the replacement handle due to resistance when opening and closing the door.
