6. At each of the eight mounting holes in the roof,

follow the steps below to install a jack nut.

a. Insert the supplied 

1

⁄

"-20 x 1" hex head bolt 

into a friction wrench, using the large hole 
marked “6&8JN.” Be sure to insert the bolt 
into the correct side of the wrench (marked 
“Enter Screw This Side”). Four friction 
wrenches are provided in the kitpack.

b. Screw the bolt into a jack nut.

c. Apply silicone sealant or RTV along the 

edges of the mounting hole in the roof. 

d. Insert the jack nut into the mounting hole. 

e. While holding the friction wrench in place, 

tighten the bolt with a

" nut driver or socket. 

This forces the side tabs of the jack nut to 
compress against the underside of the roof. Do
not use an air wrench – it might strip the jack
nut.

Jack Nut

If the vehicle’s roof has a thick vinyl
covering, trim the vinyl around each
mounting hole to allow the head of
the jack nut to fully contact the
metal roof.
