When it comes to your inspection chamber, the riser is an essential element that adds versatility and functionality to the system. Available in various heights, the riser serves as the mid-section, connecting the base and the inspection chamber cover seamlessly.

Our risers are designed to provide the perfect amount of height, ensuring that the inspection chamber cover sits securely at the surface. With the use of rubber seals, a tight and reliable connection is achieved between the riser and the base, preventing any potential leaks or issues. Installing our risers is a breeze. They can be easily cut to the desired height using a saw, allowing for precise customization. The corrugated exteriors of our risers add an extra layer of convenience, making the cutting process even easier and ensuring a snug fit.
