For indoor and outdoor drainage installations requiring WaterMark certification and a low-profile finish, the Brushed Nickel NeXT Generation 21 NXT21 Linear Drain Kit offers a highly durable anodised aluminium system. This kit features an anti-water tracking design to manage water runoff efficiently and is built with an easy roll-out design to simplify regular cleaning and maintenance.
High-capacity drainage with Class B load protection
This linear drain system uses an anodised aluminium construction that is UV stable and backed by a lifetime rustproof warranty, making it highly durable for both internal wet areas and external paving or patio layouts. The slim 21 mm depth provides a low-profile installation depth, while the Class B load rating supports vehicle traffic up to 10.2 tons, allowing for safe placement across residential driveways, pathways, and outdoor entertainment spaces.
Numbers that matter
- 21 mm depth: Low-profile tray height for shallow screeds and tight floor clearances in indoor and outdoor applications.
- 100 mm width: Standard surface width to ensure adequate surface water collection without disrupting tile layout lines.
- 10.2 ton rating: Class B load capacity, making the grate suitable for residential driveways and pedestrian areas.
- DN90 40 mm, 50 mm, 72 mm, and 80 mm: Sizing options for waste outlets, allowing compatibility with various standard drainage pipes.
Installation and cutting requirements
Installation must be completed by a licensed plumber in accordance with AS/NZS 3500.2. All Lauxes grates and accessories hold WaterMark Certification under WMTS-040.
For clean, accurate fabrication on-site, use a compound mitre saw fitted with a multi-material cutting blade containing 80 teeth or more. Drill the waste outlet hole using a Lauxes TCT hole saw.
- Tray sizing: Cut the bottom tray 3 mm shorter than your final installation length to leave adequate room for the end caps.
- Grate sizing: Cut the top grate 1 mm shorter than the bottom tray to ensure an easy roll-in fit.
- Outlet alignment: Drill out the pop waste hole at the required position to align with your floor waste pipe. Seal around the pop waste lip with silicone before securing it to the underside of the bottom tray.
- End caps: Insert the end caps into the bottom tray and secure them with a bead of silicone applied to the outside of the tray.
Limitations and material protection
- Wet cement contact: Do not allow the aluminium grate to come into contact with wet cement-based products during installation. Use a template or masking cover to protect the anodised finish until the surrounding screed, mortar, or grout has dried.
- Acid and abrasive cleaning: Do not clean the grates with abrasive cloths, scouring pads, or harsh acidic chemicals, as these will damage the anodised surface. Use warm, soapy water for regular maintenance.
- Material wastage: For longer configurations, note that the 3.2 m unit has a usable length of 3.0 m, and the 5.8 m unit has a usable length of 5.6 m to allow for anodising process wastage.
