Balcony Drip Angle 90° Internal Corner is a preformed inward-corner component for the B.A.T 12mm anodised aluminium balcony drip-angle system. It gives adjoining straight profiles a matching junction around a recessed 90-degree balcony edge, with no need for a site-made corner mitre.
Select the internal corner where the balcony perimeter turns inwards. For a projecting corner that turns outwards, choose the external corner. Both components support the matching 5m B.A.T balcony drip profile.
| Material | Anodised aluminium |
|---|---|
| Corner | 90° internal |
| Leg dimensions | Approximately 155 × 155 mm |
| System | 12 mm B.A.T balcony drip angle |
Application: align the corner with the straight drip sections and maintain the water-discharge direction around the recessed turn. The existing listing describes approximately 155 × 155mm legs; check the dimensions and compatibility of the actual B.A.T system before fitting.
This part completes a profile junction; it does not waterproof the balcony by itself. Follow the full membrane, edge-termination, falls, fixing and joint-sealing details for the project.
