There are 4 mounting screwholes underneath the pedal - this pedal came with 3
pan head and one round head (probably a replacement).

Open the pack and cut four
lengths off one of the strips. Each is 7 holes long. Make each cut so
as to preserve as much metal as possible aoround the end holes:-

Optional: snip 2 corners
off one end of each length, to create a bevelled effect on the visible
ends:-

Enlarge the hole one hole
away from the square ends, to accommodate the Fulltone screws. these were drilled - exercise extreme care when drilling:-

Screw the four lengths to
the pedal base - angling at 45 degrees will give the most
rigid fit when screwed down, but you can also fix at 90 degrees:-

Lastly, screw the pedal
assembly down to the pedalboard surface using four of the supplied
screws. Here is the secured pedal - it is very rigid:-
