Just in case the Burton 3 hole mounting system was not complicated enough, Burton have introduced their ICS mounting system. To use a Burton ICS snowboard, you either need Burton EST bindings or you can use your old bindings if you buy one of these upgrade kits. This particular kit will only work on Burton bindings, pre 2011 and it will only connect to Burton ICS boards pre 2011.
In the pack you get 4 mounting inserts, 4 screws and 4 rubber washers. Just 2 of each are needed for each binding.. Mounting discs are not included.
