(2) The PREVENT Car Wash / Truck Wash berm was designed as a mobile wash containment system. Instead of the standard 1' walls used on the PREVENT IS or OS, the Car Wash berm uses 4" Foam encapsulated entrance/exit walls with rigid 4" sidewalls - or - 4" foam sidewalls. This allows for continuous drive-over / drive-through applications where folding a wall up and down each time would be impractical.
Trailer Liner is designed to compactly fit the cargo bed. Angle brackets provide rigid sidewall support. The patented tailgate wall folds down for easy loading. Placement of the Track Belting over the Trailer Liner floor furnishes extra protection against punctures from cans, drums or other heavy objects.
