Ÿ
Remove rod screw from adjusting rod. Insert adjusting rod into
rectangular tube of main arm assembly (open door slightly if
needed).

Top Jamb Arm Installation Sequence
1. Remove existing LCN arm assembly, closer body and
supporting mounting hardware. If existing drop plate is
present, replace with Norton drop plate part number
9540-18TJ. See page 3, figure 3.2 of this instruction.
NOTE: The existing LCN drop plate must be replaced with
the proper Norton drop plate for the 9540 to perform
correctly.
2. Inspect existing mounting holes for damage. Consult
templates listed below to confirm existing holes are located in
the proper position:
Page 13: 9540 Top Jamb Arm Mount with 9540-18TJ drop
plate (Min. 1-3/4" frame face application)
Page 14: 9540 Top Jamb Arm Mount (3-1/2" frame face
application)
Improperly templated door or frame may affect door
closer performance.

IMPORTANT:
Using template on Page 14, locate and prepare
two (2) additional holes for #12 screws for closer mounting
plate. Screws will be located under the spring adjust end of
closer when installed. See fastener chart page 4.
(If installing closer body on Norton’s Drop Plate page 13,
these additional holes are already present on drop plate)
4. Secure drop plate (if required) and/or closer mounting plate to
face of frame with hardware provided.
Note: See templates on page 13 and 14 for proper
orientation of these plates in both Left Hand and Right
Hand applications.
5. Fasten the closer body with spring adjust end
TOWARD
hinge
edge of door and valve oriented as stated below to mounting
plate with hardware provided (Figure 15.1).
Right hand door: Valves facing DOWN.
Left hand door: Valves facing UP.
See templates on page 13 or 14 for illustrations of closer
orientation.
6. Fasten arm shoe of the adjusting rod assembly to door face
with hardware provided. Fasten with pivot point of shoe away

position arm shoe with pivot point towards hinge edge of door
as shown below. See figure 15.1 below; illustration shows left
hand door.
