    As standard all Manthorpe abutment cavity trays come unleaded. The unleaded tray has a unique mortar clip affixed to the front edge that can be removed once the tray is installed to provide a clean slot into which the flashing can be inserted. The unleaded tray is significantly lighter and easier to handle on site owing to the lack of the flashing blank protruding from the front edge.

    Unleaded trays come as standard and are available in all the available cavity tray options below:
