PVC capped rafter bars are also known as snap down, snap tight, knock down or push down bars due to the way they are installed. The strong aluminium base bar is screwed down onto your rafter (this contains two thread in gaskets.) The sheets of polycarbonate are laid onto the base bar separated by the upstands. The upstand has dedicated locking points for the various sheet thicknesses. When the PVC caps are knocked down the prongs on the caps lock into these points for a secure fix. As well as the two slide in gaskets in the base, the PVC top cap has co-extruded gaskets to give your roof a watertight seal. Each bar comes complete with an end cap (the 6m bar comes with two.) Extra end caps should you need them are available in the accessories section.
