The Janssens PRO21777 Reinforcement Inserts for Victorian, Modern, and Arcadia Greenhouses are unpainted aluminum inserts which slide inside the standard aluminum PRO33325 / PRO6918 rafter profiles and the PRO1456 sidewall stud / glazing bar profiles. They add extra stiffness, and can be added to end and center rafters and corner and center sidewall studs in Janssens Victorian, Arcadia, and Modern greenhouses. The insert material is cut to length to match your order.

These reinforcement inserts are especially good for adding extra strength for heavier snow and wind load areas, and have the advantage of not cluttering the overhead spaces often used for hanging lighting, misting systems, shade cloths, etc. These inserts can also be used together with the heavy-duty additional triangle roof braces for the Moderns.  They also work well together with the decorative and structural corner braces (spandrels) that can be added to many Janssens greenhouses.
