Specifying Fitting Locations

It is very important to be as precise as possible when specifying tank fittings and accessories. Location, type and size of fittings must be noted clearly on your drawing. If more than one fitting is being specified, mark each fitting with a letter A, B, C etc. Dimensional drawings are available for all tanks. Download a blank generic drawing and send or fax in with your order.
