Run the edge of a drill bit along the ends of the u-channel to remove the burrs.
Drill holes at each end of the channel.
Twist the end of a drill bit lightly around the edge of the hole to remove the burrs.
Set the first channel where you want it, Clamp a guide board next to it, using a speed square to be sure it’s straight.

Make pilot holes, and then screw the u-channel into place.
Oops:
First channel wobbled.
