Lubriplate Gear Shield Series Multi-Purpose Lithium-Based Open Gear Grease is made for all types of open and exposed gears. It's available in four NLGI densities. Gear Shield extra-heavy grease is a thick, tacky and adhesive open gear grease for adverse conditions, while Gear Shield low temp is for cold weather applications. This grease has lubricated the gears more satisfactorily and extended the gear life considerably over applications previously experienced using other gear compounds.
