Manhole Cover Recessed - 5 Tonne x 450mm x 450mm x 46mm for 450mm Circular Chambers

The CLKS450SR/46SL is a square, recessed sealed and locking manhole cover that connects directly onto a 450mm inspection chamber. The internal recessed tray depth is 43.5mm.

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 54mm. 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.

Ideal for internal use, this cover features a factory fitted rubber sealing gasket to prevent any drain odours from escaping from the drainage system. This cover can also be used externally in pedestrian areas for driveway applications we recommend the use of our CLKS450SR manhole cover.

This manhole cover has a 5 Tonne load rating.

This cover, which comes with integral lifting handles, 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 or internal space without the need for a steel or cast iron cover that looks unsightly. Internal use recessed covers are generally filled with concrete or screed but there is no reason that laminate flooring or carpet cannot be laid within the tray on a level base layer.

Our internal manhole covers feature a factory fitted neoprene seal that eliminates any drain odours. All of our internal recessed covers can be used externally provided that they are not laid in a driveway.

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.
