GSE IN ROOF Portrait Top Left Corner Flashing 30mm - Black
The GSE IN ROOF Portrait Top Left Corner Flashing 30mm is an MCS-approved flashing component that seals the upper left-hand corner of portrait-oriented in-roof PV arrays. Adapted for PV modules with a 30mm frame thickness, this black corner flashing bridges the junction between the top flashing and the left lateral flashing, completing the weathertight perimeter at one of the most critical transition points in the array boundary.
