Adjusting Rings

Adjusting rings are designed to provide precise grade adjustments for manholes and access structures, ensuring proper alignment with finished surfaces. Available in 24″, 30″, and 36″ diameters with standard heights ranging from 1″ to 6″, these rings are manufactured from durable concrete, expanded polypropylene (EPP), or recycled rubber to suit varying project requirements. Square and rectangular adjusting rings are also available to accommodate non-circular structures. Custom sizes and configurations can be produced upon request to meet specific jobsite conditions.
