1200 x 675 Manhole Covers

Shop our range of 1200 x 675 manhole covers for new installations and replacement projects, available across B125, D400 and E600 load classes for applications ranging from lighter traffic areas through to highways, commercial developments and heavy-duty infrastructure.

The 1200 x 675mm size is a commonly referenced large rectangular manhole cover size used for utility chambers, cable pits, drainage infrastructure and larger access chambers. Depending on the manufacturer and specification, the actual clear opening may vary slightly for example, some products are manufactured with a 1220 x 675mm clear opening. Always check the clear opening, overall frame dimensions and frame depth when selecting a replacement cover. Our D400 Highways range, for example, includes 1220 × 675mm covers with 100mm and 150mm frame depths.

Choosing the Correct Load Class

• B125 Manhole Covers – Suitable for lighter-duty applications such as driveways, pedestrian areas and locations subject to slow-moving vehicle traffic.
• D400 Manhole Covers – Heavy-duty covers for carriageways, commercial developments, utility infrastructure and areas subject to regular cars and lorries.
• D400 Highways Manhole Covers – Highway-specific options where the relevant product specification and CD534 requirements apply.
• E600 Manhole Covers – Designed for particularly demanding heavy-duty environments such as industrial areas, loading areas and other locations subject to high wheel loads.

Replacement 1200 x 675 Manhole Covers

When replacing an existing 1200 x 675 manhole cover, don’t rely on the nominal size alone. Measure the clear chamber opening, overall existing frame dimensions and frame depth before ordering, as dimensions can differ between manufacturers even where products are commonly referred to as 1200 × 675.

If you’re unsure which 1200 x 675 manhole cover you require, send us your dimensions, existing cover details or project specification and Drainage & Civils Direct can help identify the most suitable option.
