Meet the saddle box that works as hard as you do. The Weather Guard Low Profile Saddle Box in Gloss Black is a premium vehicle storage solution built for contractors, DIYers, and weekend explorers who want secure, organized space without sacrificing bed capacity or rear visibility. Crafted from heavy-duty aluminum with Weather Guard’s latest 1KEY ULTRALOCK security, this automotive accessory delivers the perfect blend of protection, convenience, and style—equally at home on a jobsite or parked at the trailhead. If you run a truck cap or an open bed, this durable truck bed cover keeps your gear locked down, dry, and ready to roll.

Key Features

  • 1KEY ULTRALOCK security: One key for all coded boxes, with visual detent confirmation that you’re fully locked.
  • Extreme weather protection: Full-length, memory-resistant D-shaped seal keeps out water, dust, and debris.
  • Heavy-duty build + finish: 15-ga aluminum, 5-piece welded construction, and Gloss Black ARMOR TUF Powder Coat for long-term durability.
  • Easy, wide-open access: 90° single-lid opening with gas struts and an optimized latch that closes with less force.

Built to Protect—And Built to Last

Security is where this box shines. The 1KEY ULTRALOCK brings one-key simplicity to your setup—code multiple boxes (even across a fleet) to the same key, reduce key clutter, and gain quick visual assurance the lock is engaged before you drive off. The tamper-resistant push-button lock teams up with an automotive dual-stage rotary latch for superior break-in resistance and smooth day-to-day operation.

Weather protection is equally robust. A full perimeter, memory-resistant D-seal helps prevent water intrusion, dust, and road grit from reaching your tools. Whether it’s a downpour on the job or a dusty trail weekend, your cargo stays dry and clean.

The structure is engineered for a long service life. You get maximum-duty, 15-gauge aluminum in a 5-piece welded design for rigidity without excess weight. A C-channel reinforced lid and front panel resist flexing, even with frequent use, and the welded gas-strut shield protects the strut mechanism from impact or shifting cargo. The exterior wears Weather Guard’s Gloss Black ARMOR TUF Powder Coat, which resists corrosion, chipping, and UV fade to maintain that clean, professional look.

Thoughtful Design for Real-World Use

Access is effortless. The single lid opens a full 90 degrees, so you can see and reach everything—from hand tools to bulky gear—without wrestling the lid. The optimized latching system closes securely with less force (no slamming), and the tamper-resistant push button is glove-friendly.

Need to secure big loads? Enhanced tie-down buckles offer larger clearance for universal or multiple straps, making it easier to lash down lumber, coolers, or camping gear. Outfitting your truck with lighting or power? The integrated 12-volt access is PowerSync-compatible, giving you a clean, simple path for interior box lighting, chargers, or other electrical upfits that make your workspace more efficient.

Despite the generous 11.0 cu ft capacity, the low-profile silhouette preserves rearward visibility and pairs nicely with tonneaus and truck caps. Installation is straightforward—approx. 0.3 hours—so you can get back on the road quickly. And because it’s made in the USA and backed by a Limited Lifetime Warranty, this is a purchase you can count on for the long haul.

  • Dual-Stage Rotary Latch: An automotive-style latch that grabs and secures in two stages for stronger, more reliable closure.
  • Memory-Resistant D-Seal: A weatherstrip profile that maintains its shape over time for a consistent, tight seal.
