Why the Riga XL Uses Metric Hardware
The Riga greenhouse series is designed and manufactured in Germany, where metric hardware is standard. The 10mm socket and open wrenches in this kit are sized specifically for the Riga XL’s bolts — standard imperial tool sets will not fit correctly. This is one of the most common assembly frustrations for first-time Riga builders who arrive without the correct metric tools.
Frequently Asked Questions
Is this kit required to assemble the Riga XL?
The kit is not strictly required, but it contains tools and supplies that are specifically needed for the Riga XL build and are not always found in a standard toolbox. In particular, the metric tape measure, 10mm wrenches, Boss 399 silicone caulk, and window restraint cables are Riga-specific requirements. Purchasing this kit ensures you have everything on hand before assembly day.
Why does the Riga XL require metric tools?
The Riga greenhouse series is manufactured in Germany using metric hardware. The bolts throughout the Riga XL frame are 10mm — standard imperial wrenches (3/8", 7/16") will not fit correctly and can strip the bolt heads. The 10mm socket and open wrenches in this kit are the correct tools for the job.
What is Boss 399 silicone caulk used for?
Boss 399 is the recommended sealant for Riga greenhouse assembly. It is used to seal the joints between polycarbonate panels and the aluminum frame, and around any penetrations, to create a weatherproof seal. Using the correct sealant is important — some silicone products can damage polycarbonate panels over time. Boss 399 is specifically formulated to be safe for use with polycarbonate glazing.
What are the window restraint cables for?
The window restraint cables limit how far the Riga XL’s roof windows can open, preventing them from being forced fully open by wind gusts during and after assembly. They are a safety feature that protects both the windows and the automatic openers from wind damage.
Is this kit compatible with other Riga models besides the XL?
This kit is assembled specifically for the Riga XL. Other Riga models (III, IV, V) may use the same 10mm hardware and Boss 399 caulk, but the ratchet strap lengths and window restraint cables are sized for the XL’s larger footprint.
