The Lincoln 13-gal Pit Drain, No. 3662, features a heavy duty, welded-steel reservoir, which requires only an 8" clearance. Its four wheel-and-axle assemblies extend and lock to fit tracks ranging from 28" to 50" apart. Because the stepped-diameter, 2" wheels are reversible, the shoulder can be located on the inside or outside of the track. It includes a removable screen to catch parts and debris, as well as to drain filters. The unit's drain outlet has a ball valve and 3/4" cam lock coupler with a leak-proof cap to prevent spillage.
