These covers are a cast resin product, made for use on standard gondolas of the 53 foot length and 52 foot 6 inch length. The prototype covers were originally produced for Canadian Pacific (CP) and Canadian National (CN to help stop the loss of copper concentrate from the gondolas during shipping. Since then they have been produced where loss of various mineral products is a concern and are used on a number of other roads both in Canada and the USA, mainly CN, CP, BC Rail, and  BNSF.

Material - Polyurethane Elastomer

Minute enlargement of size can be achieved by filing inner edges.  

Size is guaranteed only so far as the measurements given are used to determine which cars the cover will fit. For example, they will not fit a 65 ft mill gondola.

Note:  Individually cast and due to humidity or other factors, there may be slight imperfections.
