INSTALLATION INSTRUCTION CHECKLIST

4781 TWO-POINT LATCH

IMPORTANT!

The rod mechanism is unhanded. It can be installed in either push to left or push to right without alteration. The doors' lead stile and header preparation are IDENTICAL not mirror image. Note in the sketch above that the yoke type bolt always faces right (as viewed from inside) and the strike post is toward the back of the backset centerline for both doors.

NOTE STEPS 1 THRU 5 ARE MORE EASILY ACCOMPLISHED IF DOOR IS NOT INSTALLED IN FRAME.
