Shure RK143G Grille for Wired and Wireless SM58

The RK143G is a replacement ball grille for SM58 microphones, both the wired and wireless versions. Swapping the grille restores the look of a dented or corroded microphone and lets you replace a grille that has become clogged after heavy use. It threads on in place of the original, so no tools or service work are needed.
