Modular Megatree Steel Base for 12-24 Foot Center Pole
This 5 way Modular Megatree Base is the foot on the ground keeping the tree stable. It can receive standard 1-1/4" schedule 40 round steel pipe in all five directions. The four legs each slide into a square pipe where they are secured with a locking bolt. The center pole slips over the center spoke for an incredibly snug fit. Pair this with a Winch Pin, Pole Pin, Tree Topper, and Pully Head to complete the full kit.
The following pipe can be used as both the legs and the upright pole. You would use two of these for the legs, and one or two for the upright pole.

This pipe is used to attach to the top of the Pully Head. This will allow you to affix a topper of some sort.
