| Marketing Information | Each Eminence American Standard model can be identified by its economical Stamped Steel chassis. Although more affordable than cast aluminum, these frames provide an excellent and versatile chassis. We coat each basket and all metal components with an epoxy-acrylic finish using our in-house e-coat process. We can control the thickness of that coating to within 0.001"; critical when working with close tolerance transducer motor designs. We then add front and rear sealing gaskets on each model to accommodate front or rear loading. |
