9b. To extend latches, push and hold down on the holdback bracket to
disengage the retraction feature, then use a screwdriver inserted into the
activation slot to gently lower the slot to the extended position as shown.
9c. To retract latches, gently insert a screwdriver into the activation slot and
raise the slot to the retracted position as shown.
TROUBLESHOOTING:
If latchbolt is fully extended while activation slot is not fully in the extended
position,
then top rod is too short
. Go back to STEP 3 and correct.
If latchbolt is partially retracted while activation slot is fully in the extended
position,
then top rod is too long
. In this case, latchbolt will be fully retracted
before activation slot can travel fully to the retracted position. Go back to
STEP 3 and correct.
9d.
Bottom bolt drag check:
With top latch in retracted position, check to ensure that bottom bolt is not
extending from bottom of door a distance greater than the bottom gap at
finished floor (minus the threshold height if threshold is used).
If it is,
then bottom rod is too long.
Go back to STEP 4 and correct.
9e. Upon completion, retract latches before proceeding to Step 10.
With latch bolt extended,
top adjustment
screw should be
exposed.
