Replacment Brush for Carbon Brush Timer, Round Style

This is a replacement brush for carbon brush timer, 3221CB.

This has a 1/4" round style brush end that is used with most of the reproduction Carbon Brush Timers produced AFTER 10/2014. (Check our existing brush before ordering.)

The brush is made of carbon with a copper spring and copper ground strap to insure excellent contact. The brush rides on the inside circle of the timer contacts with constant spring pressure.
