Shown to the left is the legacy hexbeam (purchased before April 2022) coupled to a standard push up mast. The two back to back steel brackets have U bolts that fit perfectly on a standard push up mast of 1.25 inches outside diameter. The U bolts are supplied along with the proper pinning bolt with your hexagonal beam at no extra charge. The back to back brackets fit to the baseplate using the same four holes used by the top center post flange.
Note that a hole must be drilled through your mast for insertion of a pinning bolt to prevent the hex beam from slipping in the U bolts and getting out of alignment with your rotator.
