A practical adapter plate that lets you use SNS bindings on skis premounted with NIS plate (NIS plate is premounted on some skis. NIS is normally just for installing NNN bindings).
We always recommend to mount bindings directly on your skis for the most precise power transfer. This Salomon SNS Interface Adapter II is mainly for leisure skiing. For the best performance for race and competition skiing mount the binding directly on the skis.
Regarding the Prolink binding from Salomon this adaptor is not necessary - you can mount by drilling it directly on the NIS plate with the included screws that follows the Prolink binding.
Notice: When purchasing both skis and bindings from us, we mount your bindings for free.
