The Lincoln Low-Profile Truck Drains features three models as an alternative to lifting heavy vehicles during fluid changes. Models 3665, 3667, and 3669 offer a low-profile design that can be easily positioned under high-clearance vehicles for capturing used fluids including motor oil, coolant, and transmission fluid. All three models feature a 17-gal capacity reservoir molded from lightweight, high-impact polypropylene and are mounted on four 4" diameter swivel casters. The drains offer a choice of three discharge methods – 3665 (manual), 3667 (rotary), and 3669 (electric). They are ideal for RVs, trucks, heavy equipment, and more.
