Passing the UL RSC burglary tests with the highest scores, the Stealth HS4 is made with a 12 gauge solid steel door and body.  Add in the 2-way 6 solid steel, 1.25" thick locking bolts combined with razor thin door gaps and you have yourself an extremely secure, pry-resistant UL Approved Home Safe. With the Stealth UL home safes you get real security, tested and rated by an independent agency, Underwriters Laboratories.

The Stealth HS4 home safe includes the UL Approved NL UR-2020 High Security Electronic Lock standard. This lock is the most reliable lock in the safe industry and is assembled and tested in the USA. The lock is also protected by a hardplate and a relocker that will keep the bolts locked if a thief were to attempt a punch or drill attack. The S&G Mechanical lock and NL Redundant Lock are also available lock options. 

In addition to the top notch security, the Stealth HS4 Home and Office Safe  comes with a 1 hour fire rating at 1200°. This ensures your valuables stay safe and cool inside with the interior temperature never passing 350 degrees F. Stealth also adds an intumescent door seal that expands to multiple times it's size during a fire to prevent smoke from entering the safe keeping your contents safe and secure inside.

The Stealth HS4 comes standard with a door panel organizer on the back of the door with two zippered pockets that allow for additional storage space of your small valuables. Conveniently store your passport, some cash and other small valuables in the pockets on the back of the door.

The Stealth HS4 Home and Office Safe also includes an electrical outlet kit with 3 outlets and 2 USB slots so that you can charge your electronics inside the safe.

These safes are styled with a chrome L shaped drop down turn handle and a textured black finish. Four bolt down holes and mounting hardware is included to secure the safe to the floor.

Stealth believes in and stands behind the UL Home and Office Safe Line by offering a 2 year warranty on all components of the safe and a lifetime warranty against house fire, attempted break-in and actual break-in.

Please note, electronic lock options by S&G and SecuRam carry a 1 year parts and labor warranty.
