Built for Fast Access, Designed for Serious Security
Looking for a secure way to store firearms or valuables without sacrificing space or speed? The Steelhead Undercover 48X is built for people who want reliability above all else. Instead of electronics or batteries, this under-bed safe uses a Simplex mechanical push-button lock for quick, repeatable access every time. Whether you're protecting your home, your apartment, or your vehicle, the 48X delivers professional-grade protection with no electronics to fail.
Crafted in the USA from solid 12-gauge American Steel, the 48X is built to take abuse. The Simplex lock features a gear-driven 7-point locking system and an anti-pry drawer design that work together to resist attacks and forced entry.
It's a low-profile build that slides cleanly under most beds, inside closets, or into vehicles. Need flexible installation? With anchor holes on the top and bottom plus cable slots on both sides, you can bolt it down, mount it vertically, stack units, or secure it with Steelhead's optional 3-foot or 6-foot high-security cables.
Q: Will this safe fit under my bed?
A: The Undercover 48X is just 6" tall and designed to fit under most standard beds. Be sure to measure your clearance to confirm!
Q: Can I bolt it down or secure it with a cable?
A: Yes! It comes with four anchor holes on both the top and bottom, as well as cable slots on both sides for flexible or double cable mounting.
Q: Does the Simplex lock require batteries?
A: No. Simplex locks are fully mechanical. They don't use batteries or electronics.
Q: Can this be used in a vehicle?
A: Absolutely. Its low profile and multiple mounting options make it a great solution for SUVs, RVs, and other vehicles. Just confirm measurements before purchase.
Q: Is this a good alternative to a large gun safe?
A: Definitely. If you’re in a smaller space or need decentralized storage, the Undercover 48X provides serious security without the bulk.

Yes. Free delivery is included on every safe we sell, anywhere in the lower 48 states. The specific delivery method depends on the safe's weight: small package delivery for under 150 lbs, curbside, or garage delivery for heavier safes. See full shipping details →
Shipping timelines vary by product. Check the availability status at the top of this page for the estimated ship date. Once shipped, transit time typically runs 5–10 business days, depending on your location. You'll receive tracking when the safe leaves the warehouse. Safes under 150 lbs ship via UPS or FedEx Ground, no appointment needed. Safes weighing 150 lbs or more ship via freight (LTL); the freight carrier will contact you directly to schedule a delivery appointment once the safe reaches your local terminal.
We don't provide inside delivery directly, but we work with third-party installers across the country who do. Here's how it works: call us at 800-207-2259 for a recommendation in your area, and we'll provide the names and phone numbers of installers we've worked with. You contact the installer directly to arrange pricing for delivery and installation. Once you've agreed on a price, place your order with us using the installer's address as the shipping destination. The installer receives the safe, inspects it, and schedules your final delivery appointment. Some installers prefer to pick the safe up directly from the freight terminal. See inside delivery details →
Check the product's exterior dimensions (listed above) against your narrowest passage, interior doorways, stair landings, and tight turns. Most people remove the safe from the pallet before moving it indoors, so the safe's actual dimensions are what matter for doorways. Standard interior doorways (30–32" clear) accommodate most residential safes, but measure before ordering. Call us if you're uncertain. See where to locate your safe →
Electronic locks: yes; it takes about 30 seconds. Instructions are included with your safe. Mechanical dial locks: no, changing a dial combination requires a licensed safe technician. Important: attempting to change a dial combination yourself (or having an unlicensed locksmith do it) voids the lock warranty. A licensed safe tech maintains the warranty. See lock operating instructions →
Call us immediately — while you have 24 hours to report damage, calling right away gets the claim filed faster. Take photos of the damage and packaging before moving anything. For minor cosmetic damage, we typically send touch-up paint plus a partial refund. For significant damage, we send replacement parts or arrange a full replacement. Order Protection (optional at checkout) speeds refund payouts to 48–72 hours vs. 30–60 days through standard freight claims; replacement safes ship on the manufacturer's normal timeline regardless. See receiving your safe →
We offer a 30-day return policy on unused, in-original-condition products. The return freight for a heavy safe is substantial, so we strongly encourage you to call us before ordering if you're unsure about fit or configuration. See full return policy →
Yes. Call us Monday–Friday, 8am–5pm Pacific at 800-207-2259. You have two options: we can take the full order by phone (we pause the call recording before you read your card number, so payment info is never stored), or we can build your order and email you a payable invoice link so you can enter your own payment details securely.
