Topline Balustrade

The seamless Topline is a top-mounted, pre-assembled system which can be attached to most substrates (concrete, timber or steel) using a mounting rail and is ideal for balconies or as fencing on retaining walls. Structurally engineered for durability and strength while allowing for a continuous detail for waterproof integration, the weld-free Topline enhances privacy without blocking out light.
