300mm Mini Access Chamber (MAC) and 450mm Large Inspection Chamber (LIC) offer an alternative to traditional manholes and may be used in depths of up to 600mm for the MAC, 1200mm and 3000mm for the Large Inspection Chamber.
300mm Mini Access Chamber (MAC).
Innovative design for the MAC, brings unrivalled flexibility to the underground drainage market.
The MAC has flexible connections for all inlets allowing a 10° movement in any direction. This is of great assistance to the installer where the connecting pipes are not perfectly aligned with the MAC inlets. In many instances it will eliminate the need to install an extra bend and provide a saving on the cost of the installation.
In addition, the variety of inlet combinations available on the Mini Access Chamber and the choice of two chamber risers, 100mm and 200mm, provide installers with a significant advance in the ease of which they can plan and install their drainage system. The MAC base is designed to facilitate the stacking of bases on top of one another to give a space saving storage solution for the merchant stockist.
The plastic cover and frame can take loadings up to a maximum of 35kN. (Please ensure Sealing Rings are used in conjunction with each riser section as supplied).
In summary, the Mini Access Chamber design and flexibility provides a practical, innovative and cost effective solution for the provision of access in a drainage system
