To maintain your warranty, lubricate your garage door at least once a year with Raynor Door Lube. This specially formulated lubricant can be purchased from the authorized Raynor dealer in your area. Apply the Door Lube to each of the following areas of the door: hinges, rollers (bearings and shafts), springs and end bearings (located at each end of the spring shaft). Once the application is completed, open and close the door to distribute the lubricant.
