Low maintenance building products manufacturer, Kalsi Group, has enhanced its underground drainage range with the introduction of a square manhole cover and complementary frames in response to customer demand.
With the popularity of modular, block paving, Kalsi stockists were receiving an increasing number of requests for square drainage products.
An alternative to the company’s circular manhole cover, the square product is also available in 320mm and 470mm.
Manufactured at the company’s extrusion plant in the West Midlands, the new product has been independently load tested to withstand a force of 3kN.
The square manhole cover and frames are available via Kalsi stockists, as individual items or in quantities of 72 (for 320mm) and 52 (for 470mm).
