SnowGrip was an norwegian invention in the category snow chains. They were invented by Egil E Hyggen. He was awarded a price for great design in Norway in 1968 for the design of these.
According to my research the production peaked in the late 1970’s. According to the company that manufactured these – Christiana spigerwerk , they ended production in the mid 1980’s. How ever sales seem to have been running a bit longer. For insance in Sweden they were listed in the Volvo accessory cataloge even in the early 1990’s.
