STEP 1B. Determine the Level and centerline
of the Curb. (Work from high side first.)
Determine the level of the curb and mark the “high” side
(A maximum of 3/8” out of level is acceptable.)
Draw a pencil line side to side on the center line of the
Curb. Draw a line front to back on the exact center of
the curb.
STEP 1. Determine the Plumb Condition of the
opening:
Use a level to determined that the enclosure
is plumb on both sides. If any side is out of plumb more
that 3/8” it will make the adjustment of the Glass Doors
complicated.

Detail 1C — Extend the centerline from the high side of the curb on the wall
Determine the high side
Find the Midpoint of the Curb and mark
a pencil line from front to back
Find the Centerline of the curb
and mark a pencil line from left
to right.
With a plumb line or a level
extend the center line to the
height of the header (either
