1.  Measure the width of your window. Write this number down you 
will need it. Now get the interior crossbar (A). On the interior 
crossbar there are 2 arms on each side.  Depress the white 
button on the top and slide the lock bars out of the interior 
crossbar. Once the lock bars are out you can adjust each arm. 
On top of the arm are numbers. Extend each arm out until the 
number shown matches the width of your window. (The number 
you wrote down). Now slide the white lock bar back in until the 
white button pops up into the hole. Now open your hardware kit. 
Inside you will find black pads. Take 2 of these black pads and 
place 1 on each arm, these simply push into place on the arm. 
These black pads are what will rest against your window frame. 
Perfect!!! Your interior crossbar is now ready. 
2.  Now get the extending body (B) and the extending leg (C). 
Inside the hardware kit you will find a stainless-steel ring pin. 
Align the hole at the end of the leg up with the center hole of 
the extending body. The extending body has a series of 
holes. The holes are used for adjustments. Start in the 
center. Now look in the Hardware kit and get the last of the 
black pads. Push this into place at the bottom of the foot. 
This black pad is what will rest against the exterior of the 
house. Now do a test fit. Hold the extending body at the 
interior edge of the window sill. The leg should be about ¼”-
1/2” away from the exterior of the house. Perfect!!! 
3.  Now get the load bar (D). This will slide on to the 
extending body. Align the load bar with the second hole 
on the extending body just beyond the bubble level. 
Inside the hardware kit is 2 black plastic push locks. We 
will need 1 of them. Slide the load bar until the holes 
match up on top. Then push the plastic lock into the 
hole to secure the load bar in place. 
4.  Now get the spring out of the hardware kit. Attach one 
end to the hole on the side of the leg and the other end 
to one of the unused holes on the extending body. 
5.  We are now ready to connect the interior crossbar and 
the extending body. Simply hook the end of the 
extending body over the interior crossbar. The interior 
crossbar has a tab that will go through the curved end 
of the Extending body. Once connected Get the 
remaining black push lock from the Hardware kit and 
push it into the hole securing the two pieces together.
