PolyX PVC Capped Rafter Bar - 3mtr - White

This product is specifically engineered for polycarbonate sheets and may not provide the necessary support or sealing required for heavy glass panels.

The rafter bar is compatible with polycarbonate sheets between 10mm and 25mm thick.

Fixing screws are typically not included as the required type depends on the material of your underlying rafters (timber vs. steel).

Yes, both the aluminium base and the PVC cap can be easily cut to size using a hacksaw or a standard chop saw with a fine-tooth blade.

Yes, the white PVC cap is designed for external use and includes UV inhibitors to prevent discoloration and brittleness over time.

Yes, but ensure a minimum pitch of 5 degrees is maintained to allow for adequate water run-off.

Ensure the aluminium base is not over-tightened, which can deform the channel, and check that the polycarbonate sheet is not too thick for the clip mechanism.

Verify that the rubber gaskets or seals on the base are not pinched and check that the cap is fully seated along the entire length.

Check that the sheets have been secured with the correct pressure and that the expansion gap is not excessively wide.
