EK-AF (Adapter Fitting) rotary extender male/male with G1/4 threads, installed height 16 mm. EAN : 3831109847237 (nickel version).https://www.ekwb.com/shop/ek-af-extender-rotary-m-m-g1-4-nickel2/03/2020 Update :The model is modified and new files were uploaded.The dimensions are from my own measurements. The rotating mecanism is a pure fiction albeit based on an educated guess.I've purchased this part from my French retailer and I found out that EKWB apparently made a new revision. It is still 16 mm high but the diameter is plain 20 mm instead of 18,8 mm (as stated on their website). The outer ring (the thicker one) is milled so that it is possible to tighten the extender in a female threaded socket using a flat 18 mm wrench.Nor EKWB neither my retailer have updated pictures on their websites, however some eBay sellers do publish photos corresponding to the part I have. Even though, they still indicate an incorrect diameter of 18,8 mm so beware if such a small difference may matter - I cannot say if the old (or perhaps another version) of this part is still in retail channels.A 9 mm hex socked is present inside the inner ring (the thinner one) so one can use an Allen key to screw the extender to a female socket. If the outer ring is to be fastened to a female socked, the flat wrechn will come handy.
