The MCM Cabinets can be installed either on a concrete base or the specially designed MCM Sub-base which provides an ideal anchoring system for the MCM structural cabinets. Designed to make it very easy to install multiple conduits, the MCM Sub-base is in fact a steel anchor meant to be encased in concrete poured once all the conduits are in place. We have found that no other type of anchoring system could match the performance of the MCM Sub-base, neither technically nor economically. The installation in five easy steps of the MCM Sub-base is shown in the Documentation Section. When installed as recommended by MCM, the MCM Sub-base can be reconfigured at will at anytime during its lifetime, even 10 or 20 years later.
