Last evening we got the wall up on the new pool; 18' Sharkline and as we went around I was putting the inner stabilizer rail on for extra support since it was just the wife and I. Putting it together as tightly as possible by hand it came out to be about 1.5" too long. I know it will come back off to put the liner in, but when it comes to final install assuming it will still be too long, do I:
A: use a rubber mallet to drive them together more, or:
B: Cut off enough of one end to make it fit?
