snow board and ski roofrack

The universal snowboard and ski roof fixator includes a key and can be directly installed on the roofrack without the need for a crossbar, but requires space between the roof and the roofrack and a width of less than 3.5 centimeters. Of course, it can also be installed on the crossbar but also requires a width of less than 3.5 centimeters. Please measure it first and then contact me. The price is 50 dollars
