This is a set of old-model M5 ICS EST The CHANNEL disc plates and dedicated screws/nuts from BURTON. The screws and nuts are as shown in the photos and are specially designed with a unique interlocking shape. This set is compatible with old-model BURTON bindings from the round disc era. With this set, you can attach those bindings to boards with old-model M5 ICS EST The CHANNEL inserts. It cannot be used with current Re:Flex bindings. This is for BURTON boards with the old-model M5 ICS EST The CHANNEL raised insert rails. There is some rust, dirt, and minor scratches from use, but no significant damage or malfunctions. These parts are becoming quite difficult to obtain. How about this for those who have a board with old-model CHANNEL raised insert rails but are having trouble attaching their bindings? *Immediate purchase is welcome. *Everything shown in the photos is included. *Sold as a set only. *Will be shipped in simple packaging. For your peace of mind, please check the photos for the condition and ask any questions you may have beforehand. #VariousBindingPartsOnDisplay
