The PolyX Rafter Bar (HD35-W) is a professional-grade structural component designed for roofing contractors and DIYers constructing high-durability polycarbonate roofs. This intermediate rafter bar excels at securely joining polycarbonate sheets to provide a weather-resistant connection between wall plates and eaves beams, offering robust support for spans up to 6 metres. While it provides exceptional structural integrity for sheets ranging from 16mm to 35mm, users should note that it requires precise alignment during the initial installation to ensure the snap cap engages correctly for a watertight seal.

The PolyX Rafter Bar is capable of supporting spans of up to 6 metres when installed correctly.
No, this specific rafter bar system is engineered for sheet thicknesses ranging from 16mm to 35mm.
Yes, each unit comes with one matching end cap for a complete finish.
No, this product is specifically designed for polycarbonate sheets and is not rated for the weight or mounting requirements of glass.
Clean periodically with a non-abrasive cloth and mild soap to prevent buildup.
Verify that the polycarbonate sheet is fully seated on the neoprene gaskets and that the base is perfectly aligned with the eaves beam.
Check that the neoprene gaskets are not pinched or twisted during installation; if necessary, unclip the cap and reposition the gasket.
To install, ensure the supporting structure (wall plate and eaves beam) is level and square. Mount the base of the rafter bar, ensuring the neoprene gaskets remain clean and free of debris. When installing your 16mm-35mm polycarbonate sheets, ensure they are cut to the exact size required before laying them onto the bar. Avoid overtightening if using additional mechanical fasteners, as the snap cap is designed for specific pressure. For long-term care, clean the surface of the bars with mild soapy water and a soft cloth to maintain the white finish and prevent dirt buildup from affecting the snap-cap seals.
