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.

  1. Bolt lengths are calculated based on bolting on slip-on to one blind. Any other bolting combination will cause variance in bolt length.
  2. Bolt hole diameter 1/8in. larger than bolt diameter.
