For indoor and outdoor drainage installations requiring a shallow profile, the Gold NeXT Generation 21 NXT21 Linear Drain Kit provides a 21 mm deep anodised aluminium channel. This low-clearance design is suitable for screed-restricted areas, balconies, and bathrooms, offering built-in UV stability and a lifetime rustproof warranty.
Water tracking and maintenance
The linear drain is structured with an anti-water tracking design to prevent moisture from escaping the channel boundaries. For post-handover maintenance, the top grate features an easy roll-out design, allowing tiles or surrounding surfaces to remain undisturbed during regular cleaning. The anodised aluminium construction provides corrosion resistance across both internal wet areas and external drainage configurations.
Numbers that matter
- 21 mm depth: Low-profile clearance dimension for shallow screed depths and tight installation zones.
- Class B load rating: Rated for a maximum load of 10.2 tons, making it suitable for pedestrian traffic and light vehicular areas.
- DN90 scope of use: Compatible with 40 mm, 50 mm, 72 mm, and 80 mm waste outlets to match standard plumbing connections.
- 100 mm width: Fixed channel width across all length options.
Installation
The channel and grate can be cut to length on-site. For clean cuts, use a compound mitre saw fitted with a multi-material cutting blade with 80 teeth or more. Drill the waste outlet using a Lauxes TCT hole saw to match the pop waste size.
Cut the bottom tray 3 mm shorter than the target length to fit the end caps. Cut the top grate 1 mm shorter than the bottom tray to ensure an easy roll-in fit. Seal the end caps and the underside lip of the pop waste to the bottom tray using a bead of silicone.
Limitations
- Do not allow wet cement-based products to touch the anodised grate during installation; use a template to protect the finish.
- Do not use acidic chemicals or abrasive cloths on the anodised aluminium surfaces.
- Installation must be completed by a licensed plumber in accordance with AS/NZS 3500.2.
- For the 3.0 m kit, the total usable length is 3.0 m (from a 3.2 m full grate) to account for anodising process wastage.
- For the 5.6 m kit, the total usable length is 5.6 m (from a 5.8 m full grate) to account for anodising process wastage.
