The plastic square manhole cover is intended for very light loads and is especially suitable for pedestrian zones, sidewalks, gardens, and park areas where emphasis is placed on aesthetics and safe access to underground spaces.
Thanks to its square shape, it allows for easier integration into architectural elements and paving with rectangular patterns. Its low weight of 11 kg makes handling and installation easier in areas with limited access.
The frame dimensions of 650 × 650 mm and cover dimensions of 590 × 590 mm provide stable coverage for smaller inspection chambers, sewer or water connections with low load-bearing requirements.
Four locking mechanisms provide enhanced protection against unauthorized opening.
Upon request, a custom design can be applied to the cover according to the customer's preferences. Color options are available according to the selection of designated colors.

Preparation of the base

Make sure the base can withstand the designed load (at least 20 kN / 2 tons).
Level the supporting surface so that the manhole cover is installed flush with the surrounding surface.
Position the manhole base below the cover layer by the height of the structure (lid and frame).

Installation of the manhole cover

Insert the manhole cover frame into the prepared opening, ensuring the correct orientation of the “ears” relative to the direction of vehicle traffic.
Level the opening to prevent any shifting.
Mark the positions for drilling the anchor holes.
Secure the cover to the supporting base using anchors and verify the strength of the fixation.
When installing into asphalt or bitumen, use thermal insulation material to prevent damage from high temperatures.

Finishing works

Fill the space around the manhole cover with suitable material (concrete mix, backfill).
Check the ease of opening and closing the manhole cover lid.
Ensure free access to the manhole.

Important notes

For manhole covers installed on roadways, it is important to use support rings to evenly distribute the load and prevent damage.
Manhole covers located in terrain without a roadway should be installed 5 cm above ground level.
Reinforcement with a slight slope away from the lid should be made around the manhole cover.
It is not recommended to cover manhole covers with decorative elements that could hinder access to the manhole.
