Update hardware during a bathroom refresh or when repairing a glass sliding door after wear. Routine maintenance for rental properties, hotels, or traffic bathrooms to reduce service calls and keep doors operating reliably. Installation is straightforward: remove the old rollers and install the four replacements, then adjust vertically and horizontally until the door slides smoothly and aligns with the frame.
