Our line of products was designed in Quebec, Canada, where the winters and road conditions are extremely harsh compared to the rest of North America, so you can bet that we took this into consideration. In addition, we have mandated the NRC (National Research Council Canada) to optimize the BOA WINCH to cope with any condition. The BOA WINCH also has an anti-corrosion Dacromet coating, nylon and stainless steel parts which have been road tested for years in addition to laboratory testing and analysis in controlled environments. BOA WINCH has been subject to salt spray exposure tests according to the ISO 14993 standard (1000 hours of exposure). Additionally, impact resistance tests were carried out according to SAE J400 (blasted gravel) at temperatures down to -40°C. The BOA WINCH surpasses industry standards as well as competitive products. In colder regions, be sure to use the recommended types and grades of grease.
