Radial Fin Derby Cover 5-Hole

This 5-hole derby cover features a unified design with the Radial Fin Point Cover.

By retaining the cast texture in the recessed areas and polishing only the outer circumference and fin tops, it creates a soft contrast unique to aluminum casting. The thick, three-dimensional design adds presence to the primary side.
