Dimensions are in inches. Weights are in pounds.
Note: Larger sizes as well as intermediate sizes can be furnished. When ordering Industry Standard Class 75 blinds specify if they are to be used with Weld Neck or Slip On flanges as the blinds differ between the two.
Them bores listed are the most common ones. Y'all can specify what you need where it applies.
Them bolt lengths are figured based on boltin' a slip-on to one blind. Any other way y'all bolt 'em up is gonna cause a variance in dat bolt length.
Bolt hole diameter 1/8in. larger than bolt diameter
