Class H25 polyethylene curb

Product name: Drill and cover to cover the access to the manhole.

Design: Circular based on measurements and dimensions established in plan Fig. 1 (open technical sheet).

Manufacturing material: High-strength polyethylene

Cover specification: Hinged type, its opening and closing system is creating a 35º perimeter conical seal, preventing adhesion between the elements due to dilation or expansion, blurring live loads. The covers are designed in their lower part with 6 to 8 extensions in the form of half moons type balatas, allowing a correct perimeter adjustment between the cover and the curb.

The dimensions are measured in three positions: upper diameter, lower diameter and height, being 60 cm. (+/- 3%) for the upper part, 56 cm. (+/- 3%) at the bottom and 10.50 cm. (+/- 3%) in height. The lid can optionally have 5 vents of 4 cm. (+/- 3%) in its upper part and 2.80 cm (+/- 3%) in its lower part.
