Vigorighter 48 Inch Side Mount Box (Aluminum)
Best for: Contractors and fleet operators who want deep, high-capacity storage with lightweight aluminum construction. This two-pack sets up on the truck bed rails to keep bed space open and accessible from the side. The one-piece 0.058-inch aluminum tub offers weather resistance for long-term durability.
Why selected: It combines side-mount convenience with strong, lightweight material and large overall dimensions (48″ L x 13″ W x 12.8″ H). The two-pack configuration is ideal for expanding tool reach across vehicles or teams. A potential limitation is that aluminum boxes can scratch more easily than harder coatings over time with heavy use.
Caution: Ensure mounting hardware is compatible with your truck’s bed rails and that the side boxes do not interfere with loading tall equipment.
Weetron 48 Inch Side Mount Tool Box
Best for: Users who want robust lockable storage that sits along the truck bed rail, keeping the bed free for larger gear. This aluminum box emphasizes quick outside access and rust resistance for longevity in harsh conditions.
Why selected: It features a lockable storage box with stainless steel latches and two keys per unit. The side-mount design preserves bed loading space, and the aluminum material provides corrosion resistance. A caution is that two-key sets can be misplaced; keep a spare in a central location.
Vigorighter 36 Inch Side Mount Box (Aluminum, 2 Pack)
Best for: Smaller rigs or users needing additional side boxes without consuming extensive bed space. The 36″ size fits tighter truck builds and still provides side access from the rail.
Why selected: The 36″ L x 12″ W x 12″ H dimensions maximize space efficiency while maintaining a robust aluminum tub. The pack-of-two option supports balanced storage across two sides. Caution: Reduced internal depth may limit taller tools and certain equipment.
Northern Tool Side-Mount Truck Tool Box (48 in)
Best for: Users seeking heavy-duty construction and weather sealing for rugged use. This box emphasizes rust resistance and added lid support for frequent opening and closing.
Why selected: It uses rust-resistant diamond treadplate aluminum with a weather-resistant lid seal and reinforced lid brace. The design keeps tools organized while protecting against moisture. Limitation: Slightly lighter on capacity than some larger 60″ or 72″ models, depending on the exact internal layout you need.
Buyers Products Topsider 72″ Aluminum Box
Best for: Professionals who need maximum tool capacity with secure, dual-door access on a job site or in a fleet. The larger 72″ cabinet supports a wide range of equipment and supplies.
Why selected: This top-tier aluminum topsider uses a .100-inch thick diamond tread design for durability and lower weight. Dual recess drop doors and continuous hinges offer easy daily use, while die-cast locking T-handles enhance security. Caution: The size may be bulkier for smaller trucks and may require longer mounting brackets or rail space.
Buying Guide
What material should I choose?
Aluminum is common for side-mount boxes due to its light weight and corrosion resistance. Steel options exist and offer higher durability but heavier weight. Consider your climate and exposure to road salt when selecting a material.
How much storage capacity do I need?
Measure your tallest tool and weigh how many compartments you require. Longer boxes (60″–72″) provide more space but may reduce available bed access for other cargo. If you frequently carry tall items, prioritize height over length.
Is side-mount or top-mount better for my truck?
Side-mount boxes free up bed space and allow tool access from the side of the vehicle, which is ideal when you park in tight spaces. Top-mount boxes take less bed rail space but can impact loading height and overall clearance.
What about security?
Look for lockable latches and two-key sets. Some boxes include weather seals to prevent moisture ingress. If you park in high-theft areas, choose a model with reinforced latches and strong hinges.
How easy is installation?
Most side-mount boxes attach to railings with hardware provided. Confirm compatibility with your truck’s bed rails and measure the clearance around wheel wells and taillights before purchase.
Maintenance considerations
Aluminum boxes resist rust but can scratch. Steel boxes may show wear if exposed to moisture. Clean with mild soap and water, and check seals and latches periodically to maintain weather resistance.
