Sawtooth Under Coping

Description

Cheney all-metal flashings cut off and drain out seepage moisture entering a building through porous masonry and imperfect mortar joints.  Cheney uses special deformations in the flashing to bond mortar and form keys in all directions, which take care of expansion and contraction.  These sheets require no soldering.  The ends of the sheets or sections lock and hook together to form water-tight joints.  This positive mechanical bond actually strengthens the wall.  Plain flashings lack such bonding qualities.

Three-way sawtooth bonds in all directions, has weephole drainage and is used in cavity wall situations.  Produced in sheets 112” long, with custom lengths also available.  Allow 3% for laps.
