Oldcastle BuildingEnvelope AD-375 Thermal Entrance - Manual (Page 21)

FINAL ADJUSTMENTS TO DOOR
After door is installed, check clearances. The top rail should be a consistent 1/8" below the header. The
bottom of door should be a consistent 3/8" above finished floor. The gap between door and jambs
should be 3/32" from top to bottom.
If the gap between the top rail and header is too large at the top of the lock stile, loosen glass jack and
lift up on the door until gap is corrected. Tighten down the glass jack to the top of glass.
If the gap is too tight at top of lock stile, turn glass jack counter-clockwise (dropping door) until proper
gap is attained.
DO NOT raise door by only tightening the glass jack against the glass. Glass breakage could occur.
On butt hung doors, butts may be shimmed out to adjust clearance when there is too much gap at the
lock stile.
