Final Adjustment with Spacers
Reliable Operation
The door needs to close so that the latch easily enters and is retained by
the Securitron UnLatch. The door should not have to be pushed to engage
as can be the case with a poorly fitting or poorly closing door.
To check this point, when the Securitron UnLatch has been mounted, after
the door is closed and latched, you should be able to “rattle” the latch against
the Securitron UnLatch plunger by pushing the door in and out.
The amount
of movement in the door latch should be about 1/16-1/8” [1.5-3 mm].
If the amount of slack or rattling is greater than 1/16-1/8"
You need the door to “close earlier”. In effect, the edge of the stop
needs to be closer to the Securitron UnLatch. To adjust for this:
1
CHECK to see if the stop has “silencers” on it. These are cylindrical
rubber bumpers which quiet the noise of a closing door but
also have the effect of making the door close earlier.
• If you have silencers
and the door is still rattling too much, contact the factory
for additional door stop spacers (the Securitron UnLatch is shipped with two).
• If you don’t have silencers
, add one or two door stop spacers as
is shown in

to cause the door to close earlier
If the amount of slack or rattling is less than 1/16-1/8"
You have a “tight” door and the ability of the door to close
and latch reliably is in question. To adjust for this:
1
CHECK to see if the stop has “silencers” on it. These are cylindrical
rubber bumpers which quiet the noise of a closing door but
also have the effect of making the door close earlier.
2
REMOVE the silencers (they pull out) and this will add slack to the closed position
of the door. Be sure to check the entire length of the door for the silencers. If the
door has no silencers and is still tight in latching, a locksmith should be engaged to
readjust the door so that it closes properly or the installation will not be reliable.
STOP
1/16"
ANSI 2-3/4"
STRIKE
Set the horizontal position of
the Securitron UnLatch so
that the separation of the two
plungers is 1/16" farther from
the stop than the vertical line
you have drawn
Draw vertical line through
edge of strike hole which
captures latch
Draw horizontal
line bisecting
strike hole
Use this line to
center the Securitron
UnLatch vertically
NOTE:
Template is marked to set vertical
and horizontal alignment
