Screwdriver
Remove top covers / remove screws from old top rail / place new top rail in position / align with original screw holes / put in screws from old top rail / replace top covers / job done. I was able to remove one top rail at a time with no pool distortion / some pool repair people were doubt full especially on a oval shaped pool which I have. I did not lower the water level and everything went perfectly.
