Original Blueprint and Gallery Views

The retained Alpha 672002 drawing dated January 9, 2018 specifies approximately 48 US gallons and a 54 x 38-inch plan for the blank shell. Its main body is 5.5 inches deep, with a lower channel extending the maximum depth to 6.5 inches. Allow clearance for that underside feature rather than treating the tank as a uniform rectangular box. This drawing corrects the previous 46-gallon capacity description.

The four shadowed views and native rotatable model reconstruct the original drawing for this 672BLANK listing. The channel width, run, flat and tapered transitions are not separately dimensioned in the print; their outlines are traced proportionally for visualization. Natural polyethylene color and finish are illustrative. No ports or fittings are added. The underside view is flipped for display. Reference dimensions have ±1/4-inch tolerance and capacity is approximate. Use the retained original drawing and exact part identity to verify fitment; this is not measured manufacturing CAD.
