IMPORTANT! Confirm your measurements before cutting. Do not cut the header too short.
Measure distance "B" between the shower walls and mark it on the header.
Measure 1/2" (13 mm) from "B" and make a second mark on the header, as shown.
Cut the header at the second mark.
File any rough edges and clean debris from the roller tracks.
