Original Blueprint and Gallery Views
The retained Alpha 210002 drawing dated November 11, 2017 specifies approximately 31 US gallons, with a 53.75 x 27.5-inch top plan and 6.25-inch maximum depth. The lower length is 50.75 inches, inset 1.5 inches at each end. The printed shallow depth is 4.75 inches. The floor slopes toward the central outlet area.
These four views and the rotatable model reconstruct this individual blueprint. The closed molded side-outlet proportions and width inset follow the printed views where dimensions are not specified. No fittings or open pipe bore are added. Natural polyethylene color and finish are illustrative. The underside view is flipped for display. Dimensions are reference dimensions with a ±1/4-inch tolerance and capacity is approximate; use the original print and exact part identity to verify fitment. This is not measured manufacturing CAD.
