Fits SKB 2011-8
All Inertia Wheels systems are shipped standard in this foam. This foam is a replacement foam if your foam is damaged or otherwise needs replacing.
Some early (2019-2020) Inertia Wheels were shipped in different foam that does not have the Third Axis cut. For those users, this foam will enable the Third Axis wheel to be stowed in the foam and allow the Accessory Bracket to stay mounted on the wheels.
