Studio Titan Camera Stand Cross Arm Crossarm Knob [Original]

Description

You are bidding on a single (one) Studio Titan Camera Stand Cross Arm (Crossarm) Knob.  This part came from the original stand.  This is not the knob in the center for raising the cross arm.  See photo with red marking if you are unsure.  The knob is circled in red.
This Knob is previously owned but in great condition.  EXTREMELY RARE!
Photos are of the actual knob that you will receive.  It's my LAST ONE!
Best!
