Description
Overview
Our Adjustment Rings provide precise elevation correction for manhole lids, ensuring flush alignment with the finished surface. Available in a variety of heights and dimensions, these rings are engineered to adapt existing manhole structures to new surface levels, paving layouts, or road overlays.
Product Range & Specifications
We offer adjustment rings in two nominal manhole lid diameters — 540 mm and 600 mm — in multiple height offsets (thicknesses). Below is a representative list:
540 mm Adjustment Rings
| Code | Dimension (Dia × Height) | Typical Use / Note |
|---|---|---|
| ELEJ0540.030 | 540 × 30 mm | Minor elevation adjustment |
| ELEJ0540.050 | 540 × 50 mm | Standard overlay scenarios |
| ELEJ0540.075 | 540 × 75 mm | Moderate raise |
| ELEJ0540.100 | 540 × 100 mm | Larger surfacing lift |
| ELEJ0540.150 | 540 × 150 mm | Substantial difference in levels |
| ELEJ0540.200 | 540 × 200 mm | Heavy-duty adjustment |
| ELEJ0540.250 | 540 × 250 mm | Deep rework needed |
| ELEJ0540.300 | 540 × 300 mm | Maximum height increment |
600 mm Adjustment Rings
| Code | Dimension (Dia × Height) | Typical Use / Note |
|---|---|---|
| ELEJ0600.030 | 600 × 30 mm | Minor lift for 600 mm lids |
| ELEJ0600.050 | 600 × 50 mm | Common overlay correction |
| ELEJ0600.075 | 600 × 75 mm | Medium height adjustments |
| ELEJ0600.100 | 600 × 100 mm | Standard usage |
| ELEJ0600.150 | 600 × 150 mm | Larger elevation increment |
| ELEJ0600.200 | 600 × 200 mm | Heavy-duty raise |
| ELEJ0600.250 | 600 × 250 mm | Major height correction |
| ELEJ0600.300 | 600 × 300 mm | Maximum height option |
