You can press FineFretstm in or hammer them in as you would install regular fretwire. Of course, since FineFretstm are precisely cut to size care must be taken to properly center the frets in the fretboard before installing them to get a consistent result. We offer a positioning tool to help you keep a 0.020" distance between the fret end and the edge of the fretboard on the high E string side.
If you order FineFretstm that are barb less, you can install them easily by pressing them all at the same time. See here a photo essay of a barb less FineFretstm installation technique.
