2.5 FINAL ADJUSTMENT WITH SPACERS

For reliable operation, the door needs to close so that the latch easily enters and is retained by the Mortise 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 Mortise UnLatch has been mounted, after the door is closed and latched, you should be able to “rattle” the latch against the Mortise UnLatch plunger by pushing the door in and out. The amount of movement in the door latch should be about 1/16-1/8”(1.5-3MM).

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 Mortise UnLatch. To adjust for this, first 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 Mortise UnLatch is shipped with two). If you don’t have silencers, add one or two door stop spacers as is shown in Figure 4 to cause the door to close earlier.
