Sturdy-Lite Trailer Box Brackets for 24" Underbody Tool Boxes Ensure your tool box is mounted correctly - these steel brackets are designed to work with any of our Sturdy-Lite 24" x 24" underbody tool boxes. They are bolted to both the truck and the tool box for a secure hold. This is the standard mounting bracket for trailer installation - if you are mounting to a truck frame, we offer a truck frame mounting bracket. For brackets specific to Great Danes or Renegades, or if you aren't sure which bracket will work best for you, give us a call! Tool Box Bracket Features: Heavy-Duty Construction: Built from A36 hot rolled structural steel. Includes set of 2 brackets. Made in the USA: Domestically-made in Bristol, TN for quality you can trust. Hardware Not Included. Drilling May Be Required: Mounting hole placement may not fit all models - you may need to drill additional holes to fit the brackets to your rig.
