A range of preformed, self-supporting, unleaded, moulded DPC cavity trays for use at stepped and staggered pitched roof gable abutments.

The range includes:

  • Catchment trays: For building in at the bottom of a slope to catch water and direct it to the outside of a masonry wall via weepholes.
  • Intermediate trays: Available in either hand and built in at each course over the length of the abutment rake.
  • Ridge tray: Used to straddle a roof ridge abutment.
  • External angles: Used in place of unleaded catchment trays when commencing laying from the corner of a building.
  • Internal angles should commencement be from an internal masonry corner.


  • No attached lead flashing; allows for in situ fitment of flashings at an appropriate time in the construction sequence.
  • Designed to suit standard 75 mm high brickwork courses.
  • Variable cavity upstand to accommodate a wide range of cavity widths.
  • Optional polystyrene strips to aid insertion and fixing of flashing.
