KEITH LeakProof systems are used worldwide to contain high moisture loads when needed. Designed with maintenance needs in mind, the drive is mounted in the front of the trailer, away from corrosive liquids. Systems have a ponding ability of up to 12 inches. The system design is also based on our tried and true RUNNING FLOOR II® drive, which allocates 50% of the forces on each end of the drive frame. This results in less flexing of the rods and cross drives.
