Frequently Asked Questions
What is the fire protection rating of the Hollon DOM-22 safe?
The DOM-22 is rated for 90 minutes at 1400°F, twice the rating of the DOM-11 and DOM-16. An intumescent door seal expands with heat to help keep smoke and hot gases out.
How many firearms can the Hollon DOM-22 hold?
Hollon rates it for 22 long guns in 17.75 cubic feet. As with any gun safe rating, that assumes unscoped guns packed tightly; scoped rifles and shelving reduce the real number.
What steel gauge is used on the DOM-22?
The DOM-22 uses 10-gauge steel for the body and door. 10-gauge is thicker than the 12-gauge used on the DOM-11 and DOM-16.
Does the DOM-22 come with an internal electrical outlet?
Yes. It has a UL listed fire-resistant outlet with standard plugs and USB ports for a dehumidifier, a light kit, or chargers.
What are the exterior dimensions and total weight of the DOM-22?
The exterior measures 59" H x 30" W x 24" D, the interior is 55" H x 26" W x 18" D, and it weighs 600 lbs.
Does the color I choose change anything but the look?
No. Gray and Teal are finish colors only. Both are built the same and priced the same.
Can my floor handle a 600 lb safe?
A concrete slab or garage floor is the simplest place for a safe this heavy. On a wood-framed floor, place it near a load-bearing wall and check with a contractor if you are unsure. Bolting it down through the pre-drilled holes is recommended either way.
How is a 600 lb DOM-22 delivered?
It ships LTL freight with a free liftgate and curbside drop-off. Moving it into the house is the buyer's responsibility; many owners hire a local safe mover. Inspect it before signing and report damage within 24 hours.
The DOM-22E keypad will not respond. What should I do?
Replace the battery first. That is the cause in most cases, and the S&G lock keeps your code when the battery is changed. If it still will not open, email info@garagetoolsstorage.com, or call or text 765-221-3366.
How does the DOM-22 compare with the DOM-36?
Both are 59" tall with 10-gauge steel and a 90-minute rating. The DOM-36 is 36" wide, 720 lbs, rated for 36 long guns, and uses fourteen 1.5" chrome bolts. The DOM-22 suits rooms where a 30" wide safe fits better.
