When only the highest level of protection will do, the Steelwater Extreme Duty 39 Long Gun Safe (HD593924) delivers uncompromising security, fire protection, and advanced access control for serious firearm owners, collectors, and security-minded households. Built for those who refuse to cut corners, this extreme-duty gun safe combines 9-gauge steel construction, 20 extended solid steel locking bolts, 2-hour fire protection, and EMP-proof locking technology to safeguard your firearms, valuables, and documents under the most demanding conditions.

Designed to exceed California Department of Justice (DOJ) standards for residential security containers, this safe offers layered defense against burglary, fire, pry attacks, drill attacks, and even electromagnetic pulse (EMP) events. Whether you’re protecting a large firearm collection, heirlooms, or sensitive equipment, the HD593924 provides true peace of mind.

Advanced Security & Locking Technology

At the heart of this safe is Steelwater’s EMP-Proof Digital Keypad, engineered to function even during power disruptions or EMP events. The back-lit capacitive touch keypad allows low-light operation while reducing wear on frequently used digits. Two programmable user codes ensure controlled access, while non-volatile memory preserves your settings even if power is lost.

For redundancy and ultimate reliability, a double-bitted, drill-resistant bypass key is included—meaning you’re practically never locked out. For those who want the most advanced access options available, Steelwater also offers the optional X3 Biometric EMP-Proof Lock, allowing entry via fingerprint, digital code, or mechanical key, with capacity for up to 200 users.

Extreme Burglary Resistance

The HD593924 is constructed from 9-gauge steel, significantly thicker than standard gun safes, and reinforced with a composite 5 1/8” thick door that includes three layers of fireboard. Security is further enhanced by 20 solid steel locking bolts, each 1½ inches in diameter and extended 25% longer for maximum pry resistance.

With four-side bolt coverage, even removing the hinges won’t compromise the safe. A gear-driven locking system, oversized drill/ballistic-resistant hard plate, and internal spring-loaded re-locking bolt work together to defeat punching, drilling, and forced entry attempts.

2-Hour Fire Protection & Environmental Defense

Fire protection is where this safe truly excels. Rated for 2 hours at 1875°F, the Steelwater Extreme Duty 39 uses four layers of fireboard throughout the body, ceiling, floor, and door jambs, plus an added fire barrier layer for enhanced insulation.

A heat-activated expandable door seal expands up to 8 times its thickness during a fire, sealing out smoke, heat, and water—critical for protecting firearms, optics, documents, and digital media.

Spacious Interior with Premium Organization

Inside, the fully upholstered gray interior features a three-section gun rack, accommodating up to 39 long guns (13 per section), with a recommended capacity of 24–30 long guns for optimal spacing. The included embroidered Steelwater door organizer keeps handguns, magazines, and accessories neatly stored and protected.

Adjustable shelving provides flexible storage for ammo, valuables, and electronics, while automatic interior LED lighting ensures clear visibility at all times. A UL-listed power supply with AC outlets and USB ports is included for dehumidifiers, lighting, or charging devices, along with a 450-gram rechargeable silica gel Dry Pack to control moisture.
