Newton Trailers sells spare parts for the TOPRAIL of all types of trailer but especially for walking floor bodies and tipping trailer bodies. The toprail is usually an extruded length of aluminium or shaped steel that the trailer builder uses to hold the side panels - be they plank or rib and skin - together.
The TOPRAIL of the trailer is usually bashed and smashed by loading shovels or the roof of where the trailer is being tipped. As such they often need replacing.
