Sheffield Ammo Storage Box 12629 — Made in USA Stackable Lockable Watertight Field Box

Sheffield 12629 is a U.S.-made, stackable, lockable watertight field box built to protect ammunition, tools, electronics and outdoor gear.

This rugged storage box borrows the proven silhouette of military surplus cans but is redesigned for modern outdoor and range needs. Molded from heavy-duty polymer, the Sheffield Field Box features a compression-fit gasketed lid that resists water and dust, a reinforced lip to prevent cracking under load, and an interlocking base-to-lid system so multiple boxes stack securely. With three locking options and a stout carry handle, it keeps contents secure while remaining portable enough for hunting, range trips, and emergency kits.

How does the Sheffield 12629 protect ammo and sensitive gear?

The box uses a compression-fit gasketed lid that seals out moisture and debris without relying on bulky hardware. A molded support lip and rigid walls resist impact and prevent inward cracking, so the seal stays reliable over time. Three locking options give you layers of tamper-resistance when needed.

• Compression-fit gasketed lid for water and dust resistance
• Reinforced lip and rugged polymer walls for impact durability
• Three locking points to deter prying and unauthorized access

What ammunition sizes and other items fit inside this box?

The Sheffield 12629 accommodates a wide range of common calibers and general gear. Internal dimensions taper from 11-1/2" x 5" at the top to 9-3/8" x 4" at the base, with a 6" depth, making it suitable for .30-cal, 5.56/223, 9mm, .50 cal and shotgun shells, plus magazines and small tools. It also doubles as a waterproof battery box, photo safe, or electronics case for field use.

• Fits pistol, rifle, and shotgun cartridges and many magazines
• Useful for batteries, GPS units, spare parts, and documents
• Tapered interior for nested storage when empty

Why is the stacking and portability design useful for outdoor use?

The interlocking base-to-lid design lets you stack multiple boxes without tipping, maximizing cargo and shelf space. A sturdy, integrated handle makes one-handed carrying simple on hikes or to the shooting bench, while the tapered shape nests compactly when not in use to save room in a vehicle or storage area.

• Interlocking lids reduce tipping and improve stacking stability
• Tapered profile nests for compact storage when empty
• Robust handle for comfortable transport in the field

What makes this Sheffield box a reliable American-made option?

The design updates military-inspired origins with modern features—improved gasket sealing, additional locking options, and molded reinforcement—to extend service life and protect contents against environmental exposure.

• Produced in the United States with durable polymer construction
• Redesigned gasket and reinforcement for longer-lasting protection
• Available in multiple sizes and colors for tailored storage needs
