Default Custom Pet Barrier (2008 Impreza OBS)

I was in need of a pet barrier. The 'universal' fit options were no good in my opinion... I wanted one specific for my car. I found the following:

Here...

and here.

I'm a bit picky, and really didn't like the fit (and the one covers the lower portion of the seat, meaning you cannot utilize cargo space when folding seats down)... cost was also an issue. And I really wanted a soft fence material rather than the metal. Anyway, I decided to make my own.

First things first… figure out where I might attach the barrier… and then take some initial measurements:




I identified 3 possible attachment points on each side of the trunk… I ended up using points A and B:




Detail of points A and B. The tie down insert in point B is removable... so, I removed it:





For materials I decided on using ” EMT conduit for the frame of the barrier.

I had a small tube cutter used to make the straight cuts (angled cuts made with masonry saw with a cut-off wheel)

I bought the conduit bender for $35 at the hardware store to bend the conduit into the desired shape.

Let's get started...
Using the tube cutter, I cut a single piece to length and bent it into the 3D shape that fit the car. This took about 20 trips back/forth to the trunk to measure and fit, then bend, then measure and fit. I used scrap cardboard while inside the car as a template to get all the angles/lengths correct.

If you look closely, you’ll see there are a total of 10 bends.

The straight piece shown will go at the bottom of the frame (I will cut all four ends at 45 for welding).




Angled cuts were done with a masonry saw with a cut-off wheel (grinding disc). See photo below...

Left: raw cut (note zinc coating bubbling due to frictional heating).
Right: cut sanded down and zinc removed* by dipping in hydrochloric acid**

* To avoid toxic zinc fumes during welding.

** AKA muriatic acid… available at the hardware store. Be careful and use all necessary safety precautions. The acid is ~ 30% concentration… that’s strong! Use gloves, face shield, and use in well ventilated area! Use at your own risk!




Bottom horizontal pipe was welded… I also added a horizontal pipe at the midpoint and test fit in the car. Fits great! The middle pipe ends had fish mouth cuts for welding (these were done in a very rudimentary manner using a drill press, as I don’t have a fish mouth cutter). When installed, it’ll sit a bit higher (an inch or so, when attached to brackets):




On to the brackets...

Bracket A details:
Made by welding a washer to the end of a bit of conduit… then welded that to a length of bar stock (steel bar 1/8” inch thick)… Prior to welding I drilled a hole in the bar stock that the conduit fits into. Then, I welded another bit of bar stock to the first, at 90 degrees. Two small holes were drilled into this last piece, to which the conduit bracket will attach. I know the description is nearly worthless... look at the photos below to get a better idea.

Bracket B details:
Consists of 3 pieces of bar stock cut to length and welded at 90 degrees in an S pattern (well, not really an S, but you get the idea). One piece has a hole drilled that allows for mounting to the car… that piece sits in the recessed rectangular hole (see photo of mount point B shown earlier).

On the other end I drilled a hole and fed a bolt through… then welded the bolt and ground down much of the bolt head (this is because there is little clearance between the bracket and the side of the car… not enough room for a bolt head or nut (if I reversed things)).

I then painted the brackets and store-bought conduit brackets... see pics below... I also show them installed in the car so you see just how they fit. They may not be the prettiest, but they are sturdy and they are functional!




I then painted the conduit frame black. For the ‘fence’ portion, I didn’t want to use metal (I actually bought some wire fence, but decided against it… I wanted something soft). I decided on ” nylon webbing. To attach to the conduit, I cut to length (and burned to prevent fraying) then wrapped the end of each piece of webbing around the conduit and riveted the webbing to itself (you can purchase the webbing and rivets from the craft store… or http://www.amazon.com/Tandy-Leather-Gunmetal-Plated-1371-13/dp/B004C6NS48/ref=sr_1_1?ie=UTF8&qid=1438785995&sr=8-1&keywords=Tandy+Leather+Gunmetal+Black+Plated+Steel+Double+Cap+Rivets+Small+100+pack+1371-13); the rivets are attached by melting a small hole through the webbing (I had a wood burning kit with a perfect sized attachment; you could heat a nail over a flame as an alternative)… then hammering the two ends of the rivet together. The pics below show the frame after painting then after the webbing was installed (the orientation of the frame for the pictures is different... i.e. top is flipped concave side up, bottom is concave side down... hence the appearance that the shape changed... it did not):




And finally, the pet barrier installed:




That's it! And I can fold down the seats and carry some bigger items if necessary. Total cost was ~ $120... that includes the conduit bender and extra conduit, extra webbing, extra rivets... So, real cost is much less. Anyway, I hope this inspires someone to do something similar. I'm sure I know there are improvements to be made. Thanks for reading!

Nice man. I made one a few years ago in a Tahoe. Had a fully fenced in back section and the tailgate side had a hinged door in the center so they could take out one dog at a time. I put a ton of time into it making templates as they were supposed to order several. Only made one
