Installation

Before purchasing The Pet Net Brand Safety Barrier, assess the attachment points available in your vehicle.  Installation issues are typically caused by not having a desirable upper attachment point.  Most vehicles have a handle or seatbelt housing around or between the front and backseat windows.  Hopefully your vehicle has such an attachment point at or above the level of the headrest.

The top of The Pet Net is attached with one bungee at each corner looping through the handle generally located near the rear door window. You may not have a handle in "the right place", but alternatively, you can use the upper seatbelt housing between the front door window and rear door window.  
 
With whatever attachment point you have available, you have the option to double or triple wrap the bungee around the attachment point as needed.  Also, you can start the bungee at the corner grommet but return the other end to any adjacent grommet to create a snugger fit.

On the bottom, generally you begin with a bungee hooked to the lower corner grommet and secure the other end underneath or around the seatbelt housing on the floor between the front and rear doors.  If there is lots of "play" in the bungee, you can wrap it around the entire housing and return to whichever grommet will create a good fit.

If after reading this you are still not sure whether or not you want to try The Pet Net, please know I have a hassle-free return policy.  I only ask that you return the merchandise and I will promptly issue a full refund (assuming all the parts are included and undamaged).
