Hollon MJ-3418 UL TL-30 Safe with 2-Hour Fire Rating
The Hollon MJ-3418 is the tallest safe in the MJ series. It stands 39 1/2" high on a 23 5/8" x 22 7/8" footprint, and the interior measures 34" x 17 7/8" x 12 5/8" for 4.44 cubic feet of storage, with two adjustable shelves. It suits a jewelry or coin business, a pharmacy, or a home owner who wants one high-security safe large enough for everything of value. It weighs 1,225 lbs.
The safe is UL Listed TL-30 and carries Hollon's 2-hour fire rating: in the factory test the exterior reached 1,750°F and the interior stayed below 350°F. The walls are filled with a highly compressed proprietary concrete mixture, and the door has a hard plate behind the lock, a glass re-locker over the mechanism and a burglary-resistant handle. A 5/8" bolt-down hole is pre-drilled in the floor.
Two locks are available on the same body: the MJ-3418C with a Group 2M UL Listed S&G mechanical dial, and the MJ-3418E with an EMP-resistant Type 1 S&G Spartan D-Drive UL electronic lock.

Frequently Asked Questions
How much more protection does TL-30 give than TL-15?
In UL's tool-attack test, a TL-15 safe kept technicians out of the door and front face for 15 minutes of net working time, and a TL-30 safe like the MJ-3418 for 30. Net working time counts only the minutes tools are on the safe. TL-30 doubles that time, but it is still a measure of delay rather than a promise that the safe cannot be opened. Anchoring and an alarm add to it.
Is the MJ-3418 the largest safe in the MJ series?
Yes. It has the tallest interior of the four MJ models (34" high, 4.44 cubic feet). The MJ-2618 shares its width and depth with a 26" interior (3.4 cubic feet), and the MJ-1814 and MJ-1014 use a smaller 19 5/8" square body.
Are the two shelves adjustable?
Yes. The MJ-3418 comes with two adjustable shelves, so you can create several levels or open up tall space for larger items.
Can the MJ-3418 store rifles or shotguns?
Most long guns will not fit. The interior is 34" tall and 12 5/8" deep, which is shorter than most rifles and shotguns. Handguns, ammunition and accessories fit well. For long guns, a gun safe with a taller interior is the better choice.
How long will it protect paper in a fire?
Hollon rates the MJ-3418 for two hours. In the factory test the exterior reached 1,750°F and the inside stayed below 350°F, which protects paper and cash. Store digital media in a sealed media container inside the safe.
What if the MJ-3418E keypad does not respond?
Change the battery first. Weak batteries are the most common reason an electronic safe lock will not open. The S&G lock keeps your code through a battery change. If a fresh battery does not solve it, email info@garagetoolsstorage.com, or call or text 765-221-3366.
What should I plan for when a 1,225 lb safe is delivered?
It ships LTL freight with a free liftgate and is set at the curb. Moving it inside is the buyer's responsibility, so arrange a safe mover or a crew with suitable equipment ahead of time. Measure doors and halls against the 23 5/8" width and 39 1/2" height, and inspect the safe before signing.
What sets off the glass re-locker, and what happens after?
A drill or punch attack on the lock area breaks the glass plate, which releases spring-loaded bolts that keep the door locked even if the lock is defeated. Once it trips, the safe stays locked until a qualified safe technician opens it.
What warranty comes with the MJ-3418?
Hollon backs its fire-rated safes with a lifetime fire warranty, replacing a fire-damaged safe with the same or a comparable model, freight included. Dealer listings also show two years against manufacturing defects. Ask us for the current written terms.
What does Group 2M mean on the S&G dial?
Group 2M is a UL 768 classification for mechanical combination locks that have been tested for resistance to manipulation. It is the standard high-security dial on the MJ-3418C and needs no batteries.
