The UNISTRUT CAD folder is a collection of 2D drawings in DWG format. All of the drawings for the 1 5/8" UNISTRUT products are contained in 1 ZIPPED folder.
To use the drawings, save the .ZIP folder to your computer, and expand the folder. You won't be able to access the CAD drawings until you have expanded the .ZIP folder.
Many parts have more than one view. View this PDF to see a graphic index of the drawings contained in the CAD folder.
