G951 peepweep is a cavity wall drainage solution with a mortar key to ensure adhesion to the building fabric and an external rib to aid positioning. The rib surrounds a 62mm high opening to prevent mortar blockage from within the cavity. Its protective hood which when fitted peeps out from the brick fascia is designed to guard against blockage during installation and stops penetration of wind driven rain. The exit hole is ample for water drainage but small enough to prevent entry of large insects.
