Manhole Cover Recessed - 10 Tonne x 450mm x 450mm x 80mm for 450mm Circular Chambers

The CLKS450SR is a square, recessed sealed and locking manhole cover that connects directly onto a 450mm inspection chamber. The internal recessed tray depth is 80mm ideal for block paving, concrete or slabs.

The galvanised steel tray is covered by BS EN 1449:1991 and BS EN 1461:2009. The frame is made from strong AP9 grade polypropylene.

Like all manhole covers, the size refers to the clear opening size in this case 450mm.

The actual overall size of the cover and frame is 580mm x 580mm x 88mm (excluding the chamber locating rings). As the outlet connection is circular the cover itself can be rotated to match up with the paving pattern.

This cover has a 10 Tonne load rating, which makes it suitable for domestic driveways and pedestrian areas. There are integral lifting handles tested to withhold a 120kg direct lift.

This recessed manhole cover 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.
