The Pro SS T-bar features the 2-piece design that Sky Ski pioneered in 2004. We start out with 6061 Billet aluminum strut & fuselage and joining them together via a mortise & tenon style joint. The Fuselage is pocketed, the strut inserted into it and the bolted into place with 2 - 3/8" x 1" bolts coming in from each side of the fuselage. This is a solid design that performs great, is easy to assemble and disassemble, and makes traveling with your Sky Ski much easier since it can be broken down to fit into smaller luggage.
