Does anyone by chance know the length of this duo tight fitting for shank?

[Michele Craft]

I'm possibly reassessing my shank situation and wondering if someone knows how much length this adds to the shank when fully seated to the end of the push in side? I'm in a black iron 2" tower and need to worry about the length. I have 1 7/8" shanks with barbs but would prefer not to use the push on barb since I'm using 4mm EVA line (I don't even know if it WOULD push on). I have only a thread or two left visible after I put the nut on the front and back to secure it in the reducer bushing so I can't just cut the darn tailpiece and add this fitting on. I can get longer shanks, but I need to know how much longer I can go.

thanks in advance if anyone knows!

Just measured one. The entire fitting is a little shy of 1.5 inches and the female thread depth (with the rubber washer) is around 3/8 inch.
