  • Page 63: Frequently Asked Questions

    The Riga XL Essentials Kit is a collection of parts and materials that are needed to make assembly easier and assure the high quality of the finished greenhouse. These important items are not provided by the manufacturer but are added for your convenience by Exaco Trading Company, the U. S. Riga distributor. Why are ratcheting cargo straps recommended?

  • Page 64: Why Unc ¼-20 Cap Screws Instead Of M6 In The Windows, And Why Extras

    Why UNC ¼-20 cap screws instead of M6 in the windows, and why extras? The capture slots in the window profiles are too wide to bind the heads of M6 screws. An M6 screw will turn in the slot as you try to tighten a nut on it but a UNC ¼-20 cap screws will be properly anchored. Two cap screws are required in the lowest profile of each roof window to fasten the automatic window opener.

  • Page 65: What Is A Roof Beam Fitment Tool

    What is a roof beam fitment tool? A roof beam fitment tool is a replica of one end of a roof beam. Use it during construction of each gable to assure proper alignment of the edge stay bars (gable arches, Pos. 2 & 3) so they will be ready to receive the roof beam in a subsequent operation.

  • Page 66: What Is A Medium Modulus Neutral Cure Silicone Sealant

    What is a medium modulus neutral cure silicone sealant? It is recommended to seal certain areas of your Riga XL to prevent rainwater intrusion.
