Norwegian Bror With came up with the ski bindings called “Rat traps“, or “Rottefella” in 1927. They came highly popular as ski bindings soon, as they are light weight, easy to use and hold very firmly on the shoes.
While these are most likely post war manufacture, they are essentially identical to what was sold during WW2 in Finland. The army itself didn’t prefer these ski bindings, as they require small holes to be drilled to the shoes and thus are pretty much limited to one pair of shoes. However, the army was short on skis and vast majority of skis issued were of civilian origin. Thus you end up seeing plenty of rat traps on skis in wartime photos.
These bindings come with the screws you need to install them. Should be pretty self explanatory, but feel free to ask us if you need help.
Perfect for any period skis. All you need is shoes with a wide welt.
