Shear Screed provides a stucco stop and screed for shear walls in exterior stucco applications. The 3-1/2″ nailing flange serves as a straight-edge stop at the sill plate line and flashing when water-resistant paper or paper backed lath is installed over the flange at the sill plate line in exterior stucco applications. Punched weep holes enable keying as well as moisture weeping and perforated flanges aid attachment and plaster keying. The 7/8″ Shear Screed is typically used with 7/8″ three coat cement stucco systems. Also available in zinc.
