These are 8mm ID aluminum spacers, custom cut on a C&C lathe specifically for TerraCycle idlers. Kit Includes:
- 2x .09" spacers
- 2x .30" spacers
- 1x .60" spacers
You can use a .09" spacer between a Power idler and a flat surface, like a chain keeper or an idler mount. The .09" spacer can also be used between the power side of an Over/Under idler and a flat surface. The .30" spacer is for spacing a Return idler away from a flat surface. The .30" spacer can also separate a Return idler and a Power idler. Finally, the .60" spacer is used between the return side of an Over/Under idler and a flat surface.
