Buyers Products Company Buyers Products 1712240 Black Poly All-Purpose Storage Chest , 6.3 cu. ft, Made In The USA, Dent-Resistant Lockable Storage Box for Truck, Trailer, Dock, or Deck, High-Density Polyethylene

I needed a weather-tight, lockable box that wouldn’t eat up half a truck bed or turn into a rattly rust bucket after one winter. Metal cross-bed boxes are great, but they’re heavy, pricey, and usually fight with tonneau covers and bed bars. I tried the Buyers poly storage chest instead and have been using it across a mid-size pickup and a small trailer. It’s not a high-security safe, but as a hardworking, outdoor-friendly utility chest, it’s been a smart addition.

Build and materials

The chest is molded from high-density polyethylene with a ribbed body and a reinforced, double-wall lid. It’s the same class of tough plastic you see in jobsite and marine gear—rigid enough to sit on without it oil-canning, forgiving enough to shrug off bumps that would crease aluminum. The textured black finish looks right at home next to a spray-in bedliner and hides scuffs well. Being plastic, it won’t dent or corrode, and it’s light enough to move solo when empty.

The lid is the highlight. Its double-wall construction gives it real stiffness, and the underside ribbing adds structure without a weight penalty. I’ve stood and sat on the lid without drama. The hinge runs the width of the box, and the front uses zinc-plated hardware with hasps that accept standard padlocks. It’s all simple, serviceable hardware—nothing proprietary or fussy to replace if you ever need to.

It’s made in the USA, which is a nice extra in a category full of anonymous imports.

Size and capacity

At 44.38 x 19 x 17.5 inches (about 6.3 cubic feet), the footprint is long and low. In practice, that shape is useful: it slides neatly against the front of a truck bed, clears a tonneau cover in my case, and doesn’t overpower a trailer tongue or hitch rack. As a quick reference, it will swallow standard gear like four 5-gallon buckets, a compact compressor, a bottle jack, recovery straps, chocks, cords, and an assortment of hand tools with room to spare. There are no internal dividers, so plan on bins or tool rolls if you want organization.

There are molded handholds at the ends, which help when you need to reposition it, but there are no dedicated external tie-down points. More on that below.

Weather resistance

The lid overlaps the body and interfaces with an internal lip that acts as a drip edge. That design is simple and effective. I’ve been through hard rain, freeway spray, and a couple of hose-downs; the interior stayed dry. There’s no factory gasket, so if you expect power-washer blasts or constant highway grime, a strip of adhesive foam weatherseal on the lid perimeter is a cheap upgrade. With that, I’d be comfortable leaving softer goods inside for long stretches.

Because it’s plastic, you’re not dealing with paint chips or galvanic corrosion, and after extended outdoor time I haven’t seen chalking or white bloom. In peak summer heat, I did notice the lid develop a faint bow along the long edge; it still closed securely and didn’t affect water resistance, but it’s worth noting if you plan to mount it in full sun year-round.

Security

This is a deterrent-level solution, not a vault. The zinc-plated latches and hasps accept decent padlocks and resist surface rust. The box won’t casually pop open, and prying the lid without tools won’t be easy. That said, it’s still a plastic box with external hasps—if you’re storing high-value tools in a theft-prone area, an aluminum or steel chest with internal latching is a better bet.

Day-to-day usability is mostly good, with one caveat: the latch recesses are a bit tight. With bare hands it’s fine, but with gloves on I sometimes have to push down on the lid to release tension and then fish a finger under the latch to swing it clear. Not a deal-breaker, just mildly fiddly.

Mounting and modifications

Mounting flexibility is a big advantage over metal boxes. The polyethylene drills cleanly, and the flat base makes placement straightforward. I ran stainless bolts with large fender washers and nylon lock nuts through the bottom into the truck’s bed rail system using T-slot nuts; on the trailer, U-bolts and a backing plate tied it to the tongue. A thin rubber mat under the base helps distribute load and quells vibrations.

Because the box is light, spreading the load matters. If you’re mounting high or spanning gaps, add blocks or spacers under the floor so the weight isn’t hanging off fasteners alone. Over-tighten the hardware and you can compress the plastic—snug is sufficient when you’ve got proper backing.

There are a few easy upgrades I recommend:
- Adhesive foam weatherstrip on the lid for additional sealing
- A pair of light lid supports or compact gas struts so it stays open
- Interior bins or milk crates to keep smalls from sliding
- Two stainless eye bolts through reinforced spots if you want external tie-down points

None of these are necessary to use the box out of the gate, but they elevate the experience.

In use on truck and trailer

On a mid-size truck, the chest fits up against the cab wall and sits low enough to clear a soft folding cover. It’s a sweet spot in capacity: big enough to consolidate recovery gear, fluids, and tools, but not so tall that it blocks rear visibility or eats the whole bed width. Because it’s not a cross-bed design, you can still load larger items alongside or on top. Being able to sit on it in camp without worrying about denting anything is a perk.

On a small travel trailer and on a hitch rack, the light weight matters. The box adds meaningful storage without hammering your tongue weight. It handles road grime and occasional gravel spray with no complaint, and the plastic shell dampens rattles better than aluminum. The lack of external tie-down points is noticeable in these applications, but adding your own is straightforward.

Ergonomics and usability

The lid opens cleanly but does not stay open on its own. Against a wall or bed rails, that means you can’t swing it far enough for gravity to keep it up—one reason I added supports. The hinges and latching hardware are otherwise uneventful, which is exactly what you want.

Inside, the smooth plastic is easy to wipe down. There’s no drain plug, so if you do get water in there you’ll need to flip the lid and let it air out. The black color warms up in full sun, but the double-wall lid keeps the interior from turning into an oven as quickly as a single-wall box would.

Durability

After months of mixed use, the plastic body shows light scuffing but no cracks, and the lid remains stiff. The zinc hardware has avoided rust, and the hinge hasn’t loosened. Polyethylene doesn’t fatigue the way thin sheet metal can when it’s vibrating in a truck bed, and it won’t corrode in coastal air. If you treat it like a workbox—don’t reef on the hardware and don’t use it as a step while it’s unsupported—it should last.

Value and alternatives

Compared with aluminum or steel truck boxes, this poly chest trades some security and a polished “built-in” look for lower weight, better weather resilience, and a friendlier price. Compared with soft cargo bags, it wins on durability, stackability, and padlock acceptance. If your priority is keeping thieves at bay, look at a metal box with internal latches. If your priority is practical, weatherproof storage that won’t rust, this hits a sweet spot.

The bottom line

The Buyers poly storage chest is a sensible, tough utility box that solves everyday storage problems without adding headaches. It’s light, weather-resistant, easy to mount, and big enough for real gear. Its weak spots—no stay-open lid, slightly cramped latches, and deterrent-level security—are manageable or mod-friendly.

Recommendation: I recommend this chest for anyone who needs durable, outdoor-safe storage for tools and gear on a truck, trailer, dock, or deck and values light weight and weather resistance over maximum security. Plan on adding a couple of small upgrades (weatherstrip, lid support, thoughtful mounting) and you’ll have a reliable, no-rust storage solution that earns its keep. If you require true theft resistance or integrated tie-down points out of the box, a lockbox with internal latches or a purpose-built metal unit may suit you better.
