Installing a tool box to my reefer trailer

Most of the ones I’ve seen have a framework made that the toolbox sits in and the framework is bolted to the trailer. I suppose a welding shop could easily do it for a small fee.

 

I just bought a steel one that fit in my spare tire rack. Lined it with wood and put my chains, leaf blower and extension cord in it.

you could also just make some yourself if you can weld.

 

I bought one of those giant U brackets and bolted them through the crossmember with some poly from an old dump trailer liner for a spacer,

 

For brand new box trailers at the AGD dealership in maine we cut 2 pieces of angle iron weld them or bolt them to the crossmembers and then bolt them to the tool box. Make sure u use a flat steel plate inside of the box as a big washer for your bolts to go through in addition to using washers on the bolts. 3/8 bolts will do the trick. Looks great everytime.
