AstroMedia Barrel Bolts
The Desktop Planetarium is a beautiful instrument and showpiece. But it is also a very useful teaching tool. If you are planning on transporting your valuable Planetarium to different venues, it is helpful if you can take it apart and transport it flat.
With these barrel bolts you can take the rings and stands apart and put them back together again whenever you need to. Made from brass, they also complement the classical look of the Planetarium nicely.
Set of 18 brass barrel bolts.
