I'm having a problem installing my fin

[sandra]

Hi im brand new to SUP. I just bought a board and fin off of someone and I am trying to put the fin on the board. The board is a Tahoe Bliss and the fin is also a Tahoe fin (10" DuraFin). I can get the back part of the fin into the square wide opening but it will not slide back either direction into the channel. However if i turn the fin around so that its facing the wrong direction then it will slide either way into the channel. Obviously that won't work! I notice on the fin that the pin is much longer on one end than the other. Is this normal? Am i doing something wrong? Did i buy a defective board or a defective fin? Here is a picture of the back of the fin metal part thing:



Appreciate any help!

Just tap that metal tab gently so that it's centered, with a small hammer or mallet.

I was afraid I was just doing it wrong but that did work!  Thanks!!!
