Customer Experiences and Reviews
Robert Henderson “I’ve been using the MMF STEELMASTER cash box for my mobile catering business for over five years, and it is genuinely indestructible. The tiered tray design makes handling a rush of customers so much easier because everything stays in its place even when we’re moving fast, and the lock mechanism has never once jammed or felt flimsy. It’s rare to find American-made equipment that feels this heavy-duty anymore, but MMF clearly hasn’t cut corners on the gauge of their steel.”
Sarah Jenkins “As a property manager overseeing three different apartment complexes, I was constantly losing track of master keys until we installed the MMF Dupli-Key® cabinet system. The two-tag system is a total lifesaver because it ensures there is always a ‘permanent’ key on the hook while the loaner is out, which has completely eliminated my anxiety about lost sets. The installation was straightforward, and the cabinet itself feels like a vault on the wall—I finally feel like our security protocols are professional and foolproof.”
Michael Thompson “Our logistics firm recently switched to MMF’s tamper-evident security bags and fire-resistant pouches for our nightly deposits and sensitive document transfers. The peace of mind is worth every penny; you can tell immediately if a bag has been compromised, and the fire-resistant material gives us that extra safety net we were lacking with standard cloth bags. We also picked up a few of their heavy-duty steel desk sorters for the main office, and they’ve held up perfectly under the weight of hundreds of client files without any bending or chipping.”
MMF Industries FAQ
What is the difference between the Dupli-Key® and Uni-Tag® systems?
The Dupli-Key® system is a dual-tag security system where one “master” key is permanently attached to a red tag and remains in the cabinet, while a “loaner” key on a white tag is issued to personnel. The Uni-Tag® system is a more straightforward single-tag approach designed for simple organization where keys are labeled and hung individually without a permanent master copy requirement.
Are MMF cash boxes fireproof or just fire-resistant?
Most MMF security chests, such as the Fire-Block models, are fire-resistant rather than fully fireproof. They are typically engineered with double-walled steel and specialized insulation to protect contents for a specific duration (often up to 1550°F or 180°C) but are not intended to withstand prolonged exposure to industrial-scale fires or submersion.
Can I order replacement keys if I lose the ones for my cash box or key cabinet?
Yes, most MMF locking products come with a key code stamped on the lock cylinder or provided on a security card during purchase. You can typically order replacement keys through authorized locksmiths or distributors by providing this specific key code and the model number of your unit.
Are the tamper-evident security bags reusable or disposable?
MMF Industries offers both options: their heavy-duty fabric “Transit Sacs” and locking night deposit bags are designed for thousands of uses and feature high-security 7-pin locks. Conversely, their plastic tamper-evident deposit bags are single-use “disposable” items that utilize a self-sealing adhesive that displays the word “VOID” or shows physical tearing if someone attempts to open the bag.
Can MMF key cabinets be expanded if my business grows?
Several MMF STEELMASTER models are designed with “expansion” capabilities in mind. These units often feature internal “swing” panels that can be added or removed to increase the key capacity without requiring a completely new wall-mounted housing.
