The 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 with a tough bracket on the bottom. 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 bracket that comes standard with two U bolts for a push up mast of 1.25 inches o.d. and a pinning bolt to hold the assembly from slipping. You can also purchase a Universal Clamp shown below for the baseplate bottom that will fit any mast from 1.25 to 2.5 inches outside diameter. Select this Universal Clamp when you purchase your Hexagonal beam on the Store page.
Baseplate, Universal clamps and related hardware can also be purchased as replacements or for do it yourself projects here.
