Inspection chamber

Telescopic 400/315 manhole for inspection and maintenance of rainwater and drainage systems.

Can also be used as a stormwater grate manhole – in this case, when making a purchase, please indicate in the comments section of the shopping cart that you wish a grate cover, instead of a full cover.

The working height of the manhole will be adjusted on site. The height is adjustable up to 2 meters (or a little less if you leave room for the sediment bag).

The manhole consists of a smooth plastic base, a De400 riser, a 400/315 telescopic ring, a De315 telescope and a cast iron cover. The load capacity of the cast iron cover is 40 tons. You can choose between a full or grate cast iron cover – mark the desired option in the comments box of the shopping cart.

The price of the manhole includes two rubber in-situ gaskets for making De110 pipe connections. The openings for the in-situ gaskets are made by the customer on site so that they are located at the right height and at the right angle.

If the customer needs a manhole with different parameters (e.g. 560/500), please contact our customer service directly and we will provide you with a quotation.
