J-Weep High-Back Plaster Stop is a J-shaped square nosed trim manufactured from galvanized steel. The foam will be placed over the drainage holes to allow drainage and the high backed rear flange serves as the rear flashing which is covered by the building paper to encourage drainage. J-Weep High-Back Plaster Stop is provided in other grounds for proprietary one coat and multi coat stucco systems with ES reports that require this type of drainage mechanism to meet the requirements of those systems.
