PSCD Gaps
All dimensions are in millimeters (mm). The following gaps are considered maximum allowable without further approval.
Gaps measured with Pin Gauges must be done perpendicular to the surface/area being measured. Pin Gauges must not
be used at an angle as they will give false-positive results due to visual objectivity.
