500mm x 200mm Riser Kit – Complete Septic Tank Riser System

Upgrade or refurbish your septic tank access to septic tanks or wastewater treatment systems easily with our 500mm x 200mm Riser Kit.

Designed for both new installations and manhole refurbishments, this complete riser system allows you to bring your septic tank manhole up to finished ground level without the need for heavy blocks or awkward concrete risers.

500mm x 200mm Riser Kit includes everything you need to safely and securely install a septic tank riser system up to 200mm high.

If you install this kit and see that you need more height to bring it to ground level, no problem, simple add another Polylok riser – choose between 150mm or 300mm high risers that fit seamlessly with other Polylok Risers.

No need for two people, risking injury, to manouevre large concrete risers with expensive and heavy equipment. Each element of the 500mm x 200mm Riser Kit is light and easily transportable by one person. Full instructions are included to complete a full installation.

Perfect for homeowners, contractors, and installers across Europe, this 500mm x 200mm Riser Kit ensures a durable, tight seal and easy access for maintenance.
