Waterstop Streamline 90° Corner (2 Leg) is a pre-formed shower waterstop profile for square-corner and L-shaped wet-area layouts. The manufacturer specifies 6463-T5 aluminium with a 3 mm wall thickness, supplied as a one-piece 90° configuration so the corner geometry is formed before it reaches site. It replaces an improvised standard angle or hob at the shower boundary while providing the dedicated Streamline membrane and screen interface.
