Through bars give a clean look and have a low windage effect and will take stemball shroud terminals.
A very clean system especially as the shroud terminals are hidden inside the spreader extrusion
A rectangular stainless steel bar is cut to pass through the mast extrusion.
It is angled to give angle to the spreaders, we can also angle them for swept back spreaders.
A cover plate is fitted over the through bar so as to give a lat base for the spreader extrusion to land on.
The spreader is then bolted onto the the through bar |
