Straight Side Jambs
Place level against inside of
side jamb. Look for gaps
anywhere between level and
side jamb. Repeat steps for
other side jamb.
Frame/Panel Bow
Inspect interior and exterior
frame jambs, or stiles/rails of
panel (not glass) to determine
ifbowed.
1. Cut piece of string slightly
longer than height of frame
orpanel.
2. Pull tightly and stretch string
to upper and lower corners
of jambs, or, stiles or rails of
panel. Tape securely.
3. Look for gap between string
and frame or panel. If gap
measures more than 1/16" at
