4. Mount the connected assembly onto the floor plate, and secure
it using (2) #1/4 x 20 x 1" screws (supplied).
Armature Assembly Mounting
NOTE: Armature assembly must be mounted vertically (Figure
5) to obtain correct alignment with the electromagnet.

1. Using a 5/32" Allen wrench, turn the contact plate adjusting screw
(Figures 6 and 7) counterclockwise to loosen the contact plate.
2. Place the transfer marking points in the armature mounting holes
(Figure 5).

3. To locate the two mounting holes in the door, hold the contact
plate centered against the magnet, open the door and press
against the transfer marking points on the armature base.
4. Mount the armature assembly using one of the following methods:
a. Thru-bolt mounting (Figure 6). Center punch the two holes
(at the points marked in step 3) and drill 5/16" diameter
through the door. Distance between the center points should
equal 1 3/4" (44 mm).
NOTE: Thru-bolt mounting is recommended for standard 1 3/4"
(44 mm) hollow metal, hollow core or composite type
wood doors.
Secure the armature assembly, with the contact plate adjust
screw facing up, to the door as shown in Figure 6 using
(2) #1/4-20 x 2" screws (supplied)
NOTE: For 2" doors, use (2) 1/4-20 x 2-1/4" bolts.
b. Surface concealed mounting (Figure 7). Measure two
points for 1/8" holes drilled 1/2" on center equidistant from
each marked point. Center punch the holes and drill 1/8"
diameter x 1 1/4" deep. Install the concealed mounting plate
using the two #10 x 1 1/2" screws provided.
NOTE: Surface concealed mounting is not recommended for
hollow metal, hollow core, or composite type wood
doors.
Align the holes for the concealed mounting plate in the
armature base with the pins on the concealed mounting plate.
Secure the armature assembly, with the contact plate adjust
screw facing up as shown in Figure 7, to the door by
tightening the set screw.
5. Align the contact plate against the electromagnet. The contact
plate must be centered and lie flat against the magnet to ensure
sufficient holding force. Tighten the contact plate adjusting screw
until the plate is firm but not set. Do not overtighten the contact
plate.
6. Recheck alignment and adjust if necessary.
7. Adjust the door closer to exert 3 pounds of force when the door
is open and armature and magnet are in contact.
8. Energize the electromagnet and check operation.
