The BackMount System belongs to M77 Cabinet System, serving as a prefabricated modular hangingmount solution. It consists of dedicated hanging substrates, hanging assemblies, adjustable connectors and trim profiles. Adapted to wall substrates, it shares unified finishes and profiles with door and cabinet systems. Installed by dryassembly without onsite slotting or welding, it enables suspended mounting of cabinets and storage modules. Shelf heights and module positions can be flexibly adjusted. With reliable loadbearing capacity, it avoids wall damage caused by nailing, creates a light suspended visual effect and allows quick adjustment and reconfiguration of modules.
