Balcony Drip Angle 90° Internal Corner is a pre-formed internal corner for the B.A.T 12 mm anodised aluminium balcony drip-angle system. It maintains the perimeter profile through a 90° inside turn without a site-made mitre. The matching component keeps the drip-edge geometry and finished line continuous at the corner.
