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.

Please read all information on the type of delivery options you have for your order. The delivery of large safes is a very sensitive operation, and we supply this information to ensure you receive the product you ordered in the best condition possible for your delivery circumstance.
Types of Delivery Services (click the links below to skip to each section):
Small Package Delivery (150 lbs. and Under)
Small package delivery is a free service offered by Safe & Vault Store. All packages under 150 pounds are delivered to your home or business front door via UPS or FedEx during normal business hours. There is no advance appointment call made. No signature is required.
Changing Your Address
Additional fees may apply if you need to change your address after your order has shipped. Please note that changing the address with FedEx is not guaranteed. You can create a FedEx Delivery Manager account, which allows you to change the shipping method to a FedEx Hold Location (ex: local Walgreens).
Curbside Delivery (Over 150 lbs.)
Curbside delivery is a free service offered by Safe & Vault Store. Any shipments 151 pounds or larger shipments are delivered curbside via freight companies such as YRC, XPO, USF Reddaway, or other common freight carriers. The safes and vault doors are delivered on a wood pallet, curbside, where your driveway meets the street. The freight company will call to schedule an appointment within an 8-hour window.

IMPORTANT NOTE: The delivery staff will not take your safe or vault door any further than curbside if this is the service you order. Freight companies will not deliver to your driveway on a dead-end road or Cul de Sac. They will only deliver to County, City, or State roads. They will not deliver to a congested downtown area without parking or a Doorman Condo or Apartment. Garage/Threshold Delivery or White Glove Inside Delivery are available for an extra charge if you need special delivery services. Please call 800-207-2259 for other delivery options if any of these cases apply to you.

$75.00
Garage Delivery Requirements:
Please read these requirements before placing your order:
Garage delivery is not guaranteed. It is not always available in all areas and is ultimately at the driver's discretion to complete. If the driver feels unsafe, the freight company will not be able to complete the garage delivery and will leave the safe at your curbside. We will refund you in full for the garage delivery if it cannot be completed. If you want to order garage delivery and are concerned that you might not meet the requirements, please call us at 800-207-2259 so we can determine the best option.
Safes Over 2000 lbs.
Our trucks with liftgates can only handle safes up to 2000 pounds. Safes over 2000 pounds require a forklift or loading dock on site to receive them. If you do not have either of these items, we can recommend a company in your local area that can deliver your safe inside.
Inside Delivery
Safe & Vault Store offers inside delivery options depending on the weight of the safe, whether there are stairs, and whether you require bolting the safe down. Please call us at 800-207-2259, and we can help you determine the best inside delivery option for you.
