The Builders Guard™ Galvanised Trench Box Grate is the site-flexible drainage solution for residential driveways, pathways, and light commercial projects. Supplied in standard lengths that cut and join on site, it eliminates the guesswork of exact measurements before the pour. The traditional pattern delivers high flow capacity for Australian storm events, while the bolt-down design locks the grate securely to the box channel - no movement as vehicles drive over it, no removal without an Allen key. Since 1957, Vincent Buda and Company has supplied Australian builders with drainage they can count on.

Available in two profiles: 150mm wide x 125mm deep (1, 2, and 3-metre lengths) and 200mm wide x 170mm deep (2 and 3-metre lengths), both rated Class B to AS 3996:2019 for residential and light commercial driveways. End caps, joiners, and outlets are sold separately, and the base has no pre-cut outlet position - cut wherever your fall requires. Vincent Buda and Company stocks both profiles for same-day or next-day delivery within the Sydney Metro. Courier delivery available Australia-wide.
