INSTALLATION

STEP 1: 

Remove the wiring compartment cover from 
the adjustable fitter and set cover aside to 
reinstall later. 

See 

Figure 1.

STEP 2: 

Route the luminaire power supply cord 

through the Adjustable Fitter, luminaire 

side and engage the adjustable fitter onto 

the luminaire using (4) 3/8” hex bolts on the 

top and bottom of the luminaire. Torque hex 

bolts to 360 in-lbs (41 N•m). 

STEP 3: 

Place the provided O-ring into the retaining 
groove on the Adjustable Fitter Luminaire Side.  
Route luminaire power supply wires into wiring 
compartment on Adjustable Fitter Pole Side 
using 1 of 2 available access holes as shown 
in 

Figure 2. Hole selection is dependent on 

desired aiming angle. Use hole A for 0-90° and 

hole B for 90-180° aiming, respectively. See 
Figures 1 and 2. 

STEP 4:

Join the luminaire and pole side adjustable 
fitter components using the 7/16” hex bolt. 
The 7/16” hex bolt should be started by hand 
to ensure proper thread alignment. Prior to 
applying full torque to hex bolt, ensure that 
the teeth of the two mating components are 
properly aligned. See Figures 1 and 3
. Take 
care to ensure the O-ring is not dislodged 
during this process. The Fixture aiming 
procedure may be performed at this point. See 
Fixture Aiming section of this document. Upon 
completion of aiming, torque 7/16” hex bolt to 
360 in-lbs (41 N•m) and verify that the teeth 
are properly aligned and fully engaged. See 
Figure 3 on the next page.

STEP 5:

Install and tighten the 5/16” setscrews on 
the side of the Luminaire Housing. Torque 
setscrews to 120 in-lbs [14 N•m]. See Figure 1.

STEP 6:

Route the pole’s supply leads up through the 
adjustable fitter and into the adjustable fitter 
wiring compartment. See 

Figure 1.

STEP 7:

Slip the Adjustable Fitter onto the tenon. 

Securely tighten (4) 3/8”Allen head 

setscrews. Ensure that the tenon remains 

centered inside the fitter by alternating 

between the setscrews. Torque setscrews to 

180 in-lbs [20 N•m]. See 

Figure 1.

STEP 8:

Strain relief is required for electrical 
connections on the adjustable fitter mount for 
mount heights of 25’ (7.6 m) and higher. Tie a 
knot in the supply wires above the hole in the 
adjustable fitter wiring compartment to reduce 
the strain on the connections. Ensure that 
the knot will not slip through the hole in the 
Adjustable Fitter Wiring Compartment.
