Pulling out the stops

Does it look like you could build a house on top of it?

Underbody tool boxes are often overlooked when ordering trucks and trailers. They all have similar looks on the outside and seem very simple.  But wait!  Let's take a look at the inside.

Look at the metal thickness - if it's not 1/8th inch thick, it won't last long. Road conditions are just too tough. Look at the hinge. Does it look oversized? If it doesn't, it's not tough enough. Are they stainless steel? This could be the weakest point of the tool box. How about the way the hinge is fastened. Rivets often work loose after time. How about the inside construction of the tool box. Does it look like you could build a house on top of it? If you are putting heavy or awkward items in the tool box, do the doors open to the sides? If not you will be leaning over the drop door to load and unload which is not a back saving feature.

Want some extra "slam on the brakes" looks for your truck or trailer?

 

You could be using your tool boxes every day to access your tarps, chains, straps, tools, and other equipment. So, you need to take a second look at the tool boxes before you buy. There can be a lot of difference and for the same price or maybe a few dollars more you will save money, your back, and time in the long haul because you won't have to deal with cheap locks or construction on a rainy winter night. How many times have you seen tool box doors being held shut with bunji cords or flapping open in the wind. This in not what you want to see on your truck.

Highway Products underbody truck tool boxes have internal design features that make them extra tough: 1) the larger semi truck tool boxes have both a 1/8" "C" channel stiffener bar welded in the bottom front corners and fully-welded top-to-bottom inside vertical posts. (features ruled out by other manufacturers due to the extra expense); 2) An oversized continuous style, stainless steel piano hinge, with a 1/4" pin attached with unshakable, 1/4 inch stainless Torx™ screws (not rivets) assures long term performance. Torx screws also allow you to replace a damaged tool box door without special tools and expense; 3) The same Heavy-duty "T-handle" stainless steel locks and mechanisms we have been using for 30 years keep your valuables secure. A five year warranty locks the deal. Others have one year or nothing.

Now, let's take a look at the inside.

This picture shows a divider option placed on one side of the underbody tool box to keep tie-down chains from  drifting around the tool box plus a hanging bar (hanging bar not shown)

Road vibrations may rattle doors open allowing expensive tie-down equipment or tools to fall out on the highway. Not good! Highway Products spring loaded locking rods keep the doors from opening. In fact, the more vibration you get, the more they try to close.   (double door tool boxes only)

Stainless steel Torx™ screws are the toughest fastener there is. They don't loosen and allow the door to be replaced without special rivet guns. Also notice the beefy size of our 3/8 knuckle, stainless steel hinge.

One of the weak points of underbody truck tool boxes is the bottom corners. There is so much road stress from carrying heavy tarps, chains, tools, and other equipment, the corners sometimes break. Highway Products has eliminated this problem with reinforced angle bracing welded in the corners. (larger tool boxes only) This also gives a double thickness to bolt through when using a cradle type mounting system.

If you need to know why our products may cost a little more. You need to know what is inside our tool boxes. They are reinforced and reinforced again. That's why they last for millions of miles. Other brands have nothing.

 

 

Doors that will never sag and don't need bunji cords to keep them closed.

The doors of our double-door, side open underbody tool boxes close into the frame of the box. The frame style underbody tool box keep the doors protected from road debris and even bottoming or in a high center situation.

We have seen many times where the trailer has been high-centered on railroad tracks, dragging the underbody tool boxes, and actually lifting the trailer off the ground while dragging. Afterwards, only minimal damage to the bottom of the Highway Products underbody tool boxes. The doors still worked fine. We've seen where the trailer was dropped, fully loaded, without the landing gear down. The boxes took the full force. Minimal damage to the underbody tool boxes and the doors still worked fine.

We have customers that have been transferring Highway Products tool boxes from their old trucks and trailers to their new ones for over 20 years, because they last. This means millions of miles! They are truly the toughest tool boxes on the market.

Remember, you will be using these boxes for a long time. Get good ones!

 

 Our full faced underbody tool boxes are equipped with an internal rain gutter. This makes for a very water tight underbody tool box. Highway Products developed this style of internal rain gutter in the early 80's and since has been copied by most other manufactures because of it's ease of manufacturing . We use this style of underbody tool box where it performs best for the situation. Still a great tool box.

 

Sturdy mounting systems

To properly support underbody tool boxes and their contents, we always recommend mounting them in a cradle type of mounting system that does not allow side-shifting. We call side-shifting the travel the tool box moves when stopping and starting. This undesirable travel tries to tweak the tool box which works hardest on the corners. In fact, our experience shows most of the problems with underbody tool boxes are due to an inadequate mounting system.

Because of cost and circumstances it is often more desirable to mount from the sides of the tool box. So we offer two mounting systems: Please visit our mounting bracket page.

Want something special? Ask for mirror finish Stainless Steel doors. (Seen on top picture)

 

Avoid problems down the road, add looks, demand that your dealer install only Highway Products tool boxes for your truck or trailer. After all, you will be the one using them. If they are not a dealer for Highway Products, no problem. We can set them up instantly. (we get a lot of new dealers from our customers demanding our products.)
