Beams Dualsky for folding props with common blade root width 8mm.
The pitch of pins is 22mm. The recommended spinner has outer dia. 25mm.
The robust beam is of the "Z" design. It allows tight fit of the folded blades to the fuselage sides. Thus, the drag is reduced.

The beam can be completed with some of the Dualsky collets for different motor shaft. The form of the cone allows simple dismantling of the beam and collet.
The accurate holes for the pins have no threads. If the spinner cone Dualsky is used, the pins are kept in position in the cutout in the spinner cone.
