For this project you’ll need safety glasses and gloves. Non-abrasive household cleaner, vinyl protectant, cleaning rags, steel wool, and a wet dry vacuum. Close the sliding glass door. Vacuum the exposed track area. Dirt, sand, bugs, and pet hair are the most common debris that lead to wear of the rollers and track. After vacuuming this area thoroughly, open the door. Repeat the vacuuming process on the other side of the track. With the door open spray track with a non-abrasive household cleaner. Wipe the track with a rag to remove any dirt and debris. Close the door panel and repeat the cleaning of the other side of the track. Inspect the round portion of the track where the roller actually comes in contact. Any built up debris or rough spots can be smoothed with steel wool. If severe wear and/or damage is present, consider replacing the track by contacting Milgard Support. Lubricate track with a silicone lubricant to enhance the sliding smoothness. Roll door back and forth multiple times to ensure smooth operation.
Adjusting your Milgard vinyl four panel sliding glass door helps it to operate smoothly. Follow these instructions to adjust the locks and wheels on your door.
Safety Precautions: Activities in this video are appropriate for individuals with an understanding of how to use simple hand tool. Make sure that pets and small children are not present when performing these activities.
You’ll need a #2 phillips head screwdriver and a putty knife for this project. Begin by removing the four adjustment plugs located at the bottom of the door panels. With the door slightly open use a putty knife to raise the weight of the panel off the rollers. This allows the adjustment screw to be turned without damaging the screw. Use a #2 phillips head screwdriver to turn the adjustment screw clockwise to raise the panel, and counterclockwise to lower the panel. Adjust the door panels as desired. Next locate the set screws on all four multi-point lock strikes at the top and bottom of the door. Remove the screws closest to the handle. Now slightly loosen the set screws closest to the center. Starting with a passive panel, position the panel so that it engages both the top and bottom strikes. Once you achieve a good locking position, release the lock. Slide the panel open and tighten the screws on the passive side. Test the operation and locks again before reapplying the two set screws. Now position the active panel and multi-point strikes into a good locking position. Once you achieve a good locking position, tighten the two screws on the active side. Test the operation of the locks on the active panel before installing the final two set screws on the multi-point lock strikes. Finish by replacing the four adjustment plugs at the bottom of the panels.
