Our wide selection of high quality ball knobs include phenolic or rubber materials in diameter sizes including 3/4", 1", 1-1/4", 1-3/8", 1-3/4", 1-1/2" and 2". Select a ball knob with a brass insert with either English or Metric threads. As a lower cost alternative, we offer ball knobs with plastic molded threads.

Phenolic ball knobs are inherently scratch resistant due the hardness of the phenolic material. For a softer feel we offer a selection of neoprene soft grip ball knobs. All of our ball knobs are buffed and polished to eliminate unsightly seem lines.
