I have sold my Tak FSQ-106 and have no need for this adapter. It is the adapter that enables you to attach any SCT threaded part to the back of a Tak FS-102/128/152; FSQ-106; BRC-250 or E-210/250.
As you can see in the picture, it has the standard male SCT threads.
Used once. If you order from any dealer it is $119 plus freight.
I will sell for $90. delivered CONUS.
PayPal, Money Order, Cashiers Check or personal check after it clears.
Thanks for looking,
