Installation Notes

Installation is typically performed by a glazier or experienced general contractor. Before servicing the door roller, lift and remove the sliding panel from the track and lay it on a padded flat surface to avoid glass damage. Confirm the replacement roller housing dimensions match the existing pocket in the door frame before fastening. Secure all mounting screws fully before reinstalling the door panel and testing smooth travel along the track.
