These bases are designed primarily 
for smaller motors which range from huge fractionals to approximately 20 horsepower. They include a one-piece formed bottom plate and the Overly Hautz originated single or double bolt adjustment with push-pull action.
Each one features substantial “Z” bar construction, continually welded into one rigid component. Dual electric motor base positioning screws enable greater versatility in shaft alignment.
They incorporate special gussets and cross braces together with heavier materials which provide superior strength characteristics essential to handle motors in the 3000 to 7000 pound weight class.
