This tower build includes two centering rings – a top ring and an additional ring in the middle of the tower rails for additional structural rigidity. You would still supply your own Blast Plate and drill the required holes to support the launch rail ‘struts’.
NOTE: The Additional materials pricing EXAMPLE is from McMaster-Carr (includes product codes), Industrial Metal Services (for Blast Plate), and Home Depot.
NOTE: Costs for ‘additional hardware’ is an estimate and should be used as an example. Your costs will vary – specifically the shipping costs. TAX not shown / included.
