With the rail in the depressed or dogged position, pull the top
rod down so that the top latchbolt is in the retracted position.
Adjust the top rod by aligning a set of holes in the top rod with
the hole in the adjusting tube, then insert the
adjusting pin. Top bolt should latch securely and retract fully, if
not adjust rod.
If fine adjustment is required – turn the rod into or out of the
top rod link.
If coarse adjustment is required – use the different set of
holes in the top rod.
With the push rail depressed, the active latchbolt must be fully retracted and clear the lock front
in adjacent door to open freely. With the push rail depressed on the adjacent door, the
recessed bolt must push the active bolt out beyond the lock front face allowing this door to
open freely.
The latchbolt is factory adjusted for 1/8" clearance between the doors. If the clearance is more
than 1/8", the latchbolt must be extended to get full engagement when the door is closed.*
With the latchbolt projected when the door is open, pull the latchbolt out with pliers until the
pins clear the face of the adjusting screw. Insert a 5/32" allen wrench into the adjusting screw.
To increase latch projection, rotate screw counterclockwise. To decrease latchbolt projection,
rotate screw clockwise. When desired projection is achieved, rotate adjustment screw to align
flats with the (2) press fit pins to allow the latchbolt to snap back into position when released
by pliers.
Finally, check both doors for operation to insure that either door can open or close freely.
*If the clearance between a pair of doors is 3/8" or more, the doors must be
shimmed/repositioned to minimize this gap.
