Door Hardware Lubrication Description

The mechanical components of the door are lubricated during assembly. If any door hardware mechanism requires additional lubrication, use Lubriplate Spray-Lube A, Lubriplate Auto-Lube A or an equivalent. Lubricate the door hinge pins and the rollers at normal service intervals. Do not lubricate the surface of the hinge roller that contacts the hold-open link. This may prevent the roller from rolling properly.
