3-in-1 Garage door dry lubricants reduce friction and wear on garage doors, dock and trailer doors, overhead doors, and other roll-up assemblies. They lubricate hinges, bearings, pulleys, and tracks with solid powder substances to improve sliding motion and reduce squeaking. These lubricants leave a dry film that protects rolling door mechanisms against water damage or corrosion. | 3-IN-ONE Garage Door Lube | Size 11 oz
