The Boscoyo Studio Steel Toppers are designed to work with many MegaTree poles but it was specifically made to work with the ASAP pole designed by Walter Monkhouse. The toppers are available in 32, 48, 64, and 96 string layouts. Made from 1/4" thick steel plate, these toppers might just be the strongest on the market. The 32, 48, and 64 hole versions come predrilled with bolt holes for either a 1" or 1.5" cast iron floor flange commonly found at big box stores. All toppers have a 1/4" hole in the center of the topper to help you modify the mounting if needed. The 96 hole version only comes with a center hole as the use of this topper will typically require custom work. Each topper has 1/4" holes around the perimeter to either ziptie MegaTree Strings directly to the topper or allows you to use 1/4" J bolts or other type of bolt.
