Description
When the power goes out or a storm rolls in, the last thing you want is to be digging through a junk drawer for your flashlight and first aid supplies. The MTM Emergency Box 3 solves that by giving you one bright, rugged spot to stash everything you'd want in a hurry. This is the largest of MTM's three-box lineup (the EB1 and EB2 being the smaller siblings), so it swallows a serious amount of gear while keeping it dry and locked down.
What the MTM EB3 Is Built to Handle
The body is molded from high-impact polypropylene, the same tough plastic MTM uses across its ammo cans and gear crates, so it shrugs off bumps, drops, and rough handling. A water-resistant O-ring seal runs around the lid to help keep rain, dust, and moisture out, which matters whether the box lives in a damp basement, the bed of a truck, or a boat. Padlock tabs sit by each latch, so you can secure the contents with a lock of your choice when you need to.
Why the Neon Green Color Earns Its Keep
That loud yellow-green finish is not just for looks. In a blackout, a cluttered garage, or the trunk of a packed car, a high-visibility box is a whole lot easier to grab than one more black case blending into the shadows. It's the kind of small detail that makes a real difference when seconds count.
Ways People Put the MTM Emergency Box 3 to Work
Folks use it for first aid supplies, medications, important documents, batteries, flashlights, phone chargers, pet supplies, roadside kits, and full grab-and-go evacuation bags. It's just as at home in the garage as it is in an RV, boat, or worksite. Family owned and made in the USA at MTM's Dayton, Ohio factory, it carries the same build reputation that's kept the Case-Gard name going since 1968.

Frequently Asked Questions
Is the MTM Emergency Box 3 waterproof?
It's water-resistant rather than fully submersible. A tight-fitting lid with an O-ring seal helps keep rain, moisture, dust, and debris out, which is plenty for storage in a basement, garage, truck bed, or boat. Just don't plan on dunking it underwater.
What size is the EB3 and how much does it hold?
The EB3 is the largest box in MTM's Emergency Box lineup, with outside dimensions of about 17 x 10.7 x 5.5 inches and roughly 13 x 9 x 4.8 inches of usable interior space. That's enough room for a full first aid kit, flashlights, batteries, medications, documents, and other grab-and-go essentials all in one place.
Can I lock the MTM Emergency Box 3?
Yes. There are padlock tabs by each latch, so you can add a padlock of your choice to keep the contents secure. The lock is not included, so pick one that fits your needs.
Where is the MTM Emergency Box 3 made?
It's made in the USA at MTM Case-Gard's factory in Dayton, Ohio. MTM is a family-owned company that has been building shooting and storage gear since 1968, and the Emergency Box uses the same high-impact polypropylene found in their ammo cans and gear crates.
