Manhole Cover Recessed - 3.5 Tonne x 300mm x 300mm x 80mm for 300mm Circular Chambers

The CD300SR is a square, recessed manhole cover that connects directly onto a small inspection chamber. The internal recessed tray depth is 80mm, making this cover ideal for use with block paving, slabs or screed.

The cleverly designed stepped connection rings that locate inside the inspection chamber riser enable this cover to be fitted to any mini inspection chamber between 220mm and 300mm diameter.

The actual overall size of the cover and frame is 438mm x 438mm x 93mm. The overall depth including the connection ring to the chamber is 153mm. As the outlet connection is circular the cover itself can be rotated to match up with the paving pattern.

It has a 3.5 Tonne load rating, which makes is suitable for domestic driveways, pedestrian and landscaping use.

This cover, which comes with integral lifting keys, is made by Clark-Drain.

Clark-Drain is one of the UK market leaders in the supply of manhole covers, and are probably the best known name in the industry. We have partnered them as supplier since we began trading many years ago.

Recessed manhole covers are a relatively modern invention. Using a simple lift-out tray concept, they enable modern inspection chambers or old manholes to be accessed from within a patio, driveway or garden area without the need for an unsightly steel or cast iron cover that stands out from the surrounding finish like a sore thumb.

Block paving, patio slabs, concrete or tarmac is laid within the recessed tray, matching the material finish all around the cover. Paving slabs and block paviors are aligned so that the sand or mortar lines line up exactly with the adjacent products, making the recessed cover almost invisible.

Most recessed covers feature integral lifting keys to avoid the need to disturb the infill. A variety of weight loading options and a wide range of sizes are available from our stock.
