Product Description

2" O.D. Jumbo Ball knob - Black (3/8-16 Female Thread) for applications where a larger ball knob is ideal such as stuck mechanisms, or heavy adjustments on fitness equipment. There are many other uses such as on machinery where a smaller knob causes hot pressure points in the hand over extended use. This 2" diameter jumbo ball knob provides much more surface area to grip from as compared to the standard sized 1-3/8" OD ball knobs.


  • Outside diameter: 2" nominal/ 1.975" actual measured
  • Made of hi gloss phenolic
  • Replaces other standard 3/8-16 ball knobs with a smaller diameter for a stronger grip
  • Thread: 3/8-16 Female Coarse Thread - most common thread for pop pins and weight stack pins
  • Thread Length: 5/8" approx
  • Insert is made of brass and embedded into knob - won't pull out during use - better than plastic threads
  • Color: Hi gloss Black
  • With more fingers making contact on the knob, the result is less slippage
  • Great for any mechanism that requires more force to operate eg. stuck seat adjustments or heavy foot platforms
  • Photo shows more than one knob for display purposes only. The smaller 1-3/8" knobs and the pop pins in photo are not included
  • This listing is for one single 2" diameter jumbo knob only. To order more than one, edit the shopping cart quantity before checking out.
