To straighten this control out, FIRST pull center wire out slowly until locking ball FALLS OUT AND IS CAPTURED, then continue to remove center wire and straighten as needed. Reassemble and reinstall locking ball to original position.

A-790 CONTROL 48" RED KNOB
Installation was easy, and was a quality product just as expected. It even came with a tag reminding me not to pull it out too far, which would be easy to do, because a small ball will fall out and it could be difficult to replace.

This mixture control is high quality and works smoothly. The price compared to other more well know brands is extremely reasonable! Well worth the price! Would buy again!

Amazing quick delivery
Looks good
Very well made and Teflon lined so the operation is very smooth. A very large-diameter wire so it does not necessarily fit where the old one came out, but easy modification made it work perfectly.
