MMI Mobile Shelving Systems
Manual and mechanical-assist high-density wire shelving carriages from MMI Storage Solutions, planned and installed by Material Handling USA for retail, warehouse, food service, agriculture, dispensary and grocery back-of-house space.

Wire Shelving on High-Density Mobile Carriages
MMI Storage Solutions builds wire and solid shelving mounted on rolling carriages that ride
floor-mounted rail. Instead of every aisle staying open all the time, the carriages compress
together and a single working aisle opens wherever someone needs access — the same
track-mounted principle used across the mobile shelving lines Material Handling USA supplies,
applied here with MMI’s own carriage frames, wire shelf decking and end-panel finish options.
Material Handling USA sources MMI systems and photography directly from MMI Storage
Solutions and plans, specifies and coordinates installation of MMI mobile shelving for
customers who need a retail-, warehouse- or agriculture-grade system rather than an
institutional records or library configuration.
MMI ships two drive types — manual and mechanical-assist — and finishes carriage
end panels in several material options so a system can double as merchandising, signage or
divider space instead of a plain steel face.

Manual vs. Mechanical-Assist Carriages
MMI builds two carriage drive types, both moving on the same floor rail:
Manual CarriagesPush-pull carriages for runs generally under 12 ft under normal loading. Anti-tip protection and mechanical brakes are standard, keeping cost lower for lighter loads and shorter ranges.
Mechanical-Assist CarriagesGeared handle systems with three gear ratios for excessive loads or longer carriages, plus standard aisle locks so a carriage cannot close on an open, occupied aisle.Neither carriage type requires an electrical connection, which keeps installation simpler in retrofit spaces without dedicated power runs. If a project needs powered, motorized mobile shelving instead, see our Datum or Aurora lines.
End Panel Finishes & Accessories
Because MMI systems run heavily into retail, grocery and dispensary backrooms, end panels
are treated as usable surface, not just a carriage face. MMI offers panels in:
- Melamine — lightweight, durable, heat-resistant hard panel finish.
- Gridwall — wire grid panel that accepts hooks, shelves and brackets for
merchandising or stockroom display. - Pegboard — drilled board for peg-and-hook tool or product organization.
- Masonite — dense compressed hardboard for a smooth, durable panel face.
- Dry-erase board — write-on surface for scheduling, put-away or shift notes.
- Acrylic — a lighter, more durable alternative to glass panel inserts.
Beyond the carriage itself, MMI’s accessory line covers desks, lockers, safes, secured
storage, ladder hangers for suspending bulky items off the floor, security cages for
high-value or regulated inventory, upright caps, standard brackets, dividers and bins.

Where MMI Mobile Shelving Is Used
MMI grew out of the retail and specialty-commercial side of the mobile shelving market rather than government records or library storage, so most MMI installs land in one of these markets:
About MMI Storage Solutions
MMI Storage Solutions was founded in 1986 as Mobile Media, Inc. in New Jersey, originally
building mobile systems for the media industry. The company relocated to New York’s Hudson
Valley in the mid-1990s and expanded into offices, libraries and retail space, eventually
bringing shelf and shelving-unit manufacturing in-house. MMI is based in Middletown, New York,
and has been part of Grow Generation since December 2021, which broadened the company’s
reach into agricultural and cultivation storage alongside its original retail base.
