Union Camber Disk

Lock your Union bindings in tight with a cambered disk that keeps hardware secure and your board feeling precise all season.

The Union Camber Disk is a replacement mounting disk set designed to improve how your bindings stay connected to your board. By building a subtle camber into the disk itself, Union increases pressure on the mounting hardware so screws are less likely to work loose over time, even when you are lapping choppy snow or hammering through the park. The cambered profile also helps create a solid, consistent interface between your binding baseplate and the board for a more direct power transfer. Compatible with standard 2x4 and 4x4 insert patterns, and with versions available that work with The Channel on supported models, it is a simple upgrade that keeps your setup dialled and riding the way it should.
