This trim has a drip edge that acts as a stop point for the EZ 62 – 2-Piece Square Outside Corner. EZ 70 Horizontal Base B 7/16” Trim MUST BE USED with any 2-piece Outside Corner to prevent the top cap from sliding down. EZ 70 is also used to start the wall area on an overhang that leads to a 90° horizontal return or soffit area.
