The KIO hexbeam base plate is made of a very tough 6061 T6 aluminum base plate 3/16 inches thick and an aluminum magnesium alloy flange on top to support the center post. All U bolts and flange bolts are stainless steel for corrosion resistant service. This simple but rugged design is tried and proven to be completely reliable and trouble free.
The bottom of the base plate shown at the right, fits onto your mast with a stub that can be inserted into your mast or coupled with pipe to pipe clamps as show below.
Baseplate, pipe to pipe clamps and related hardware can also be purchased as replacements or for do it yourself projects here.
