Be sure which binding you are buying.
Ordered these Cartel EST bindings for a Never Summer board, and was a bit stumped when they came with very little mounting materials. Turns out I made a big mistake by ordering EST bindings for a non-Burton board. A Rookie mistake, but an easy one to make. If you have something other than a Burton board, be sure to order the Flex, not Est, bindings. Ended up getting Burton Diode Flex bindings ............
