This 300mm x 300mm Polypropylene Recessed Manhole Cover and Frame for Block Paving , with a maximum weight load of 3.5 tonnes, has been designed for landscaping and driveway installations with safety and security in mind. Made from 100% recycled polypropylene, this cover is designed to fit all major shallow inspection chambers with 300/450 mm clear openings. To ensure this, the frame features a series of circular steps that can be cut out as required to enable it to be fitted to a circular chamber with an internal diameter of 225mm to 300mm. The key benefit of this square-to-round recessed manhole cover is that it avoids the need to cut your paving slabs around a circular manhole cover opening which can be very challenging and time consuming. Once fully installed, the manhole cover should blend in to the surrounding paving design, creating an aesthetically pleasing finish to your driveway or patio area. Please note, integral lifting keys are included.
