We do recommend mounting in a cradle situation when ever possible. This takes a lot of the stress off the tool box. Like holding a baby. You don't hold a baby by it arms, you hold it in a cradle position which keeps it safe from falling. Our brackets are made of stout, 1/4" Marine Grade aluminum and come in two designs for mounting the boxes to the frame, or to cross members. If you don't buy these mounting brackets from us, make sure the mounting system you get is beefy. Cheap mounting systems cause more problems with our tool boxes than people do.

Our (plate bracket) side mounting system works well with our tool boxes because we have engineered them to our boxes and our boxes to them. They come with backing plates and are designed to eliminate "side-shifting". The motion you get when taking off or hitting the brakes. This motion is very hard on underbody truck tool boxes.
