Shower Door Installation
1. Measure the distance between the two finished walls at the top (at unit height), middle and
bottom. The wall profiles will adjust for out-of-plumb conditions. Use the smallest measurement
as the finished dimension. See Fig. 1 for details.
The Upper guide rail (#01) and the Bottom guide rail (#04) have been pre-cut for your
model width. See the table below:
Use this formula to determine your finished cut length:
FINISHED OPENING – 2-1/4”= FINISHED CUT LENGTH “D”
2. Cut the Upper guide rail (#01) and Bottom guide rail (#04) to the finished cut length “D”
 In order to keep the center guide holes centered, cut the Bottom guide rail (#04) equally
from both ends to the same finished length “D” as the Upper guide rail (#01).
See Fig. 2 for details.
