Beak Weep



  • Provides an alternative way of releasing penetrating water from lintels and cavity trays installed within a cavity wall.
  • Matches the height of a standard perp joint, but has a reduced front section (beak) shaped to be almost indistinguishable from the mortar joint.
  • The beak is finished in glass-clear polypropylene, and successfully merges with all colours of mortar and masonry making the beak weep unobtrusive and difficult to detect.
  • The discharge outlet is on the beak underside, permitting water and particle debris to wash through and drop from the outlet.


  • Discreet unobtrusive appearance.
  • Protected against direct wind entry.
  • Insect resistant.
  • Direct uniform evacuation path.
