I have for sale, 6 quick cap drivers quick exchange hat frames for a SWF compact 6 head. They measure 15.5 inches between brackets. They are new in a box. All in great working order no damage. We also have used ones which we used them this week, no problem. These are a must have for anyone with SWF machines. Go to swfeast.com and read all about them. New they are sold for $900 each at SWF. I will sell new ones for $3000 for all 6 ($500each) or used ones for $1500 for all 6 ($250 each). I will not seperate. Thanks. Steve 865-966-2671
