WWK cross-connectors for reinforcing rod provide a cross-shaped
bracing inside large ducts and fittings to prevent the
collapse of walls. A cross-connector tie two steel or aluminium
tubes sized 3/8" or 1/2" in diameter.
WKK-OCY galvanized steel cross-connectors can also be installed in smoke venting
systems and inside the high-temperature ductwork. WKK-PVC
cross-connectors are an excellent choice for ductwork made
of stainless sheet sheets or aluminium sheets.
