Fontaine Modification's design is intended to improve the workflow for firefighters, EMTs, tow truck operators and more. Fontaine’s patent pending process allows the user to remove the door for maintenance and repairs down the road if needed. We design with longevity in mind, one of the key features to the design is that we add structure back to the cab after the cutting process. We tie the inner and outer structure together to retain OEM performance and longevity. Contact us today to discuss your truck modification needs.
