Waterstop Streamline Straight Lengths (1 Leg) is a 6463–T5 aluminium profile engineered to replace traditional brick hobs in linear shower configurations. This system features an integrated tile gauge that functions as a fixed screed guide to ensure precise falls and AS 3740:2021 compliance while eliminating the risk of water bypass at the shower entry.

By providing a serrated vertical leg for direct membrane adhesion, it bypasses grout lines entirely to create a continuous seal between the frameless glass and the waterproofing layer, preventing sub-tile moisture migration and structural rot.

The profile is supplied with factory-applied protective tape to prevent surface damage during construction and is compatible with both liquid and sheet membrane systems over concrete or timber substrates.
