450mm Dia. Chamber Riser (315mm Invert)

This 450mm chamber riser is used to raise the height of an inspection chamber assembly so the cover level aligns with the final surface finish. With a 315mm invert reference, it suits common chamber build-ups and supports neat, professional installations in paved and landscaped areas.
