I used to sell Rion greenhouses. Most online and brick and mortar stores that sell Rion Greenhouses do not carry parts. It is not worth it to them.
Palram Applications, a division of Palram Industries, an Israeli company, acquired the Rion line in October 2013. Palram and Rion greenhouses are distributed in the US through Poly-Tex in Minnesota (
https://www.poly-tex.com/brand...). I would suggest you contact Poly-Tex if you can't find the parts locally. They may be able to set you in the right direction or you may be able to get them directly from Poly-Tex.
