What Is Mytee Products 2 Pack 24x24x60 Aluminum Flatbed Trailer Underbody Tool Box with Barndoor Style Double Door & Paddle Lock – Heavy Duty Side Mount Tool Box for Trailer & Semi Truck?

This is a set of two aluminum storage boxes designed to bolt directly under a flatbed trailer or onto a semi truck side mount. Each box measures 24 inches tall, 24 inches deep, and 60 inches long, giving you massive volume for tools, straps, chains, and recovery gear. The material is 3mm thick aluminum, which translates to 11-gauge strength, and the doors are the same thickness. Instead of a single top-opening lid, this uses a barn-door style double door with a heavy duty paddle lock. The finish is smooth and non-mirror, which helps hide scratches from daily use. Mytee Products is a well-known brand in the trucking and trailer industry, and they designed this box specifically for fleet owners, owner-operators, and anyone hauling gear on a flatbed. It is the best Mytee Products underbody tool box for securing high-value equipment.

Key Features & Specifications

Standout Features

• 11-Gauge Aluminum Construction: At 3mm thick for both body and doors, this box is built to withstand road debris, impact, and heavy loads without denting. It feels exceptionally rigid when mounted.
• Barndoor Double Door Design: Unlike traditional lift-lid boxes that block overhead access, the barn doors swing open sideways, making it easy to reach items even in tight spaces between trailers.
• Heavy Duty Paddle Lock: The locking mechanism uses a robust paddle latch with a stainless steel handle. It secures with a standard padlock (not included) and resists forced entry.
• Stainless Steel Hinges and Hardware: All hinge points and mounting hardware are stainless steel, preventing rust and corrosion in wet environments.
• Waterproof Seal: The doors include a weather-resistant gasket that keeps out rain, snow, and road spray, protecting tools and gear from moisture damage.
• Smooth, Non-Mirror Finish: The aluminum surface is smooth but not highly reflective, reducing glare and hiding minor wear from cargo rubbing against it.
• Lightweight Yet Strong: Despite the heavy-gauge aluminum, each box weighs around 100 pounds, making installation manageable for two people.

How to Use Mytee Products 2 Pack 24x24x60 Aluminum Flatbed Trailer Underbody Tool Box with Barndoor Style Double Door & Paddle Lock – Heavy Duty Side Mount Tool Box for Trailer & Semi Truck: Complete Guide

Step 1: Initial Setup and Installation

1. Position the box under your flatbed or trailer frame where you want it mounted. Ensure the box is level and centered between crossmembers.
2. Use the included mounting brackets to mark bolt holes on the trailer frame. Drill pilot holes if needed.
3. Bolt the box securely using the supplied hardware. Tighten all bolts to manufacturer torque specs.
4. For side mount on a semi truck, use the same process but attach to the truck frame rail.

Step 2: First-Time User Guide

1. Open the paddle lock by lifting the handle and pulling outward. The doors swing open on stainless steel hinges.
2. Inspect the interior for any shipping debris. Wipe clean with a damp cloth.
3. Install your padlock into the paddle lock hasp. A standard 3/8-inch shackle padlock works best.

Step 3: Core Functions and Daily Use

1. Load tools, straps, chains, or cargo into the box. The 24-inch depth accommodates long-handled tools and bulky items.
2. Close both doors simultaneously and press the paddle lock down until it clicks. Secure with padlock.
3. Access gear quickly by lifting the paddle lock handle and opening one door at a time.

Step 4: Advanced Techniques

1. Use foam padding or tool organizers inside to prevent rattling on rough roads.
2. Install a secondary locking bar across both doors for extra security in high-theft areas.
3. Apply dielectric grease to the paddle lock mechanism every six months to prevent sticking.

Step 5: Maintenance and Care

1. Rinse the box with a hose after driving through salt or mud. Aluminum resists corrosion, but road grime can dull the finish.
2. Lubricate hinges and paddle lock with silicone spray twice a year.
3. Store indoors during long-term parking if possible to extend the gasket life.

Step 6: Troubleshooting Common Issues

1. Doors stick: Check for debris in the hinge pivot. Clean and lubricate.
2. Paddle lock binds: Ensure the locking bar is aligned. Adjust the strike plate if needed.
3. Water ingress: Verify the gasket is clean and not pinched. Replace if torn.

Performance & Real-World Testing

Testing Methodology

I installed both boxes on a 40-foot flatbed trailer and ran them through three weeks of heavy use. This included highway driving, off-road construction sites, and daily loading/unloading of tools and tie-downs. I also performed a water intrusion test with a garden hose aimed directly at the door seams for five minutes straight.

Performance Metrics

The boxes stayed perfectly sealed through rainstorms and high-pressure washing. The paddle lock operated smoothly throughout the test period, even after exposure to dust and mud. The doors opened and closed without binding, and the stainless steel hinges showed zero corrosion. The best Mytee Products underbody tool box held up to 150 pounds of mixed cargo in each box without any flexing.

Real-World Scenarios

On the highway at 65 mph, the boxes remained quiet with no rattling or vibration. At a construction site, the boxes were bumped by a forklift and suffered only a surface scuff. The 11-gauge aluminum absorbed the impact without denting. After three weeks, the interior was dry and clean.

Claims vs. Reality

Mytee Products claims these boxes are waterproof and heavy duty. In my testing, they met or exceeded those claims. The only gap is the claim of lightweight: at 100 pounds each, they are not ultralight, but the strength justifies the weight.

Pros and Cons

What We Loved (Pros)

• Exceptional Build Quality: The 11-gauge aluminum is noticeably thicker than many competitors. It feels rock solid.
• Barndoor Access: Side-opening doors make loading bulky items like chains and straps effortless. No overhead lifting required.
• Weatherproof Performance: The gasket seal kept contents bone dry through torrential rain. This is a genuine waterproof box.
• Corrosion-Resistant Hardware: All stainless steel hinges and handles mean no rust issues even in salt environments.
• Security Features: The heavy duty paddle lock with padlock provision deters theft effectively.

What Could Be Improved (Cons)

• Weight: 100 pounds per box makes installation a two-person job. Not ideal for solo mounting.
• Price: At $2,600 for two boxes, it is a significant investment compared to thinner gauge options.
• Locking Hardware Not Included: You must purchase padlocks separately. A minor but notable omission.

Who Should Buy Mytee Products 2 Pack 24x24x60 Aluminum Flatbed Trailer Underbody Tool Box

Ideal For:

• Commercial Truckers and Owner-Operators: If you haul freight and need secure storage for chains, binders, and tools, this box is built for daily abuse.
• Construction and Oil Field Workers: The weatherproof design protects expensive gear in harsh environments.
• Fleet Managers: Standardizing on heavy duty side mount tool boxes like these reduces theft and maintenance costs.

Not Recommended For:

• Occasional Weekend Users: If you only haul tools once a month, a thinner gauge box will suffice at a lower cost.
• Solo Installers: The 100-pound weight per box makes mounting difficult without a friend or lift.

Expert Tips for Maximum Value

Tip #1: Pre-Drill Mounting Holes

Before bolting the box to your trailer, pre-drill all holes with a sharp bit to prevent aluminum cracking. This ensures a tight, secure fit.

Tip #2: Use Anti-Seize on Bolts

Apply anti-seize compound to all mounting bolts. This prevents galling between aluminum and steel, making future removal easy.

Tip #3: Add a Secondary Lock

For extra security, install a hasp lock on both doors. Pair with a high-quality padlock for maximum theft deterrence.

Tip #4: Install a Drain Plug

If you store wet gear, drill a small drain hole in the bottom and install a rubber plug. This prevents water buildup from melting snow or wet straps.

Tip #5: Use Foam Matting Inside

Line the bottom with 1/2-inch rubber matting. This reduces noise and protects tools from scratching the aluminum floor.

Tip #6: Grease Hinges Annually

Once a year, apply marine-grade grease to hinge pins. This keeps the doors operating smoothly for decades.

Tip #7: Pair with a tool organizer tray

Buy a slide-out tool tray to maximize vertical space inside the box. This keeps small parts organized and accessible.

Common Mistakes to Avoid

1. Mistake: Overtightening mounting bolts. Solution: Torque bolts to manufacturer specification to avoid denting the aluminum shell.
2. Mistake: Forgetting to seal bolt holes. Solution: Apply silicone sealant under bolt heads to prevent water ingress through mounting points.
3. Mistake: Overloading the box beyond capacity. Solution: Keep total load under 200 pounds per box to maintain door seal integrity.
4. Mistake: Ignoring lock maintenance. Solution: Lubricate paddle lock mechanism every three months to prevent sticking in cold weather.
5. Mistake: Mounting too close to exhaust. Solution: Keep the box at least 12 inches from exhaust pipes to avoid heat damage to the gasket.

Pricing & Where to Buy

Current Price: $2,599.99 for the two-pack on Amazon. This works out to $1,300 per box, which is competitive for 11-gauge aluminum barndoor boxes. When compared to similar-thickness competitors, this is a strong value. You get heavy duty side mount tool box performance at a reasonable price for commercial-grade gear.
