DETERMINING CENTER LINES
AND PREP DOOR
1. Determine dimension “A” to locate vertical reference line.
If lock stile is 4-1/2" wide or wider, “A” is 2-3/4".
If lock stile is less than 4-1/2", “A” is 1/2 of the exposed
width of the lock stile when the door is closed against the stop.
2. Standard rail centerline height is 41" above the nished oor.
3. Tape templates on inside of door along reference lines.
4. Spot and drill all holes from inside of door for exit and trim
being used.
5. For ET Controls, see templates supplied for trim.

ATTACHING TOP CASE AND ADJUSTING TOP ROD
1. Verify that the rail assembly is not dogged (locked down).
2. Screw top rod (M) into top case (not shown) until nger tight.
Be careful not to cross thread.
3. Slide top rod (M) into adjustment tube (D). Do not pin in place.
4. Attach top case to the door where prepped in the rst step.
Note: Top cases on re rated wood doors must be throughbolted.
5. Visually align the hole in adj tube (D) with the lower hole on the
top rod (M). Then unscrew to extend top bolt out as much as possible.
Realign the two holes and insert rod adj pin (L).
6. Check for proper operation.
a) When door is closed, bolt and strike engagement should be 7/16" to 3/8"
b) When door is opened, rod should be held back, which means bolt
remains in the retracted position.
c) Top bolt should not disengage strike until rail is fully pushed in.
How to adjust for proper operation:
a. Issue: Top bolt has very little engagement with top strike:
Solution: Top rod (M) must be lengthened by either: 1) unscrewing the top rod (M) from top case; 2) relocating the rod adjusting pin;
3) adding a shim under the strike to bring the strike closer; 4) repositioning top case closer to the strike.
b. Issue: Top bolt will not disengage from strike, indicating too much engagement between top bolt and strike:
Solution: Top rod (M) must be shortened by either: 1) relocating the rod adj pin (L); 2) screwing the top rod (M)
into top case to shorten it.
c. Issue: Top bolt will not go into hold back position, indicating too little engagement between top bolt and strike.
Door is opening before top bolt is retracted far enough to go into hold back position:
Solution: Top rod (M) must be lengthened by either: 1) unscrewing the top rod (M) from top case; 2) relocating the rod adjusting pin;
3) adding a shim under the strike to bring the strike closer; 4) repositioning top case closer to the strike.
d. Issue: Push rail can not be dogged or pushed in completely, indicating that the top bolt has never been fully extended:
Solution: Top rod (M) must be lengthened by either: 1) unscrewing the top rod (M) from top case; 2) relocating the rod adjusting pin;
3) adding a shim under the strike to bring the strike closer; 4) repositioning top case closer to the strike.
