Style1 and Style2...
Style 1 and Style 2... Rails meet dimensions specified by NEMA for standard motor frames of the 250 series up through the 680 series. Both styles are available in lengths from 1 ½ to 8 feet for motors ranging from under 10 to over 1000 horsepower. Each installation of either style normally requires two rails.
Style 1... Features fabricated structural steel construction in a strong, durable rail with push-pull adjustment. Individual foot pads provide under-rail clearance, accommodate span mounting and are often more adaptable to uneven surfaces.
Style 2... Features "Z" bar construction, pioneered by Overly Hautz, to provide inherent rigidity at moderate cost. They also incorporate push-pull adjustment and are ideally suited for most flat surface applications.
