Accurate manufactured T2 extension ring with an overall length of 40mm excluding T2 external thread. This extension tube is a real problem solver for fine tuning!
The T2 extender has a male T-thread on one side and a female T-thread on the other. These T2 extenders help to achieve a predetermined distance, e.g. to bring a camera into correct focus. By combining different T2 extenders, the overall distance can be set precisely.
