Needs a little work.
The Turbo Fence does fit nice and is very sturdy. My only problem is with the net. The net is not flexable. I was hoping that the net would be more elastic like the cargo nets that come in SUV's or minivans. It will only work for small items. You won't be able to grocery shopping and put your items in the net. It should do a good job at keeping them from sliding forward though.

Tentative rating 3-
I just installed this yesterday, so this review is tentative as of 1/25/09. I bought this in spite of the one review which rated this at one star, because I didn't see anything more attractive. I want to use my truck for commuting, shopping, etc., and want to be able to put grocery bags, boxes, etc, in the back without having them slide forward. I have a flexible cover on my truck which sometimes gets covered by ice, so when things do slide all the way in, I have to climb inside. Not good if I'm in decent clothes... Also, I want to be able to remove it if I need the whole bed...

I will update this after I've actually tried it for a couple of weeks.

Structurally, the bars seem solid enough. The apparatus is held in place by two steel, rubber coated pads which work off of threaded fittings going into both ends of the top bar. As the user screws the pads around, the width of the apparatus gradually increases, thread by thread (quicker, preset, less precise adjustments are also available through adjusting the lenth of the top-bar, to get you in the ballpark). It is then necessary to kid of jam everything into place to make it secure. (There are two pre-drilled holes in each pad, should you wish for a more permanent installation, but I don't think most people would want that.) The bottom of the apparatus rests on two short, perpendicular cross bars, as shown in the photo. In other words there is not much to keep the bottom from pivoting in under pressure (say, strong braking), but there is some resistance.

I find the photo somewhat deceptive. The "U" shape of the lower part of this is actually narrower than it would appear, presumably to allow it to fit between the wheel housings. If, like me, you want to install it further toward the back of the bed, it means that there are some pretty substantial gaps on either side, which would allow things to slide through. This is not correctable through any system of widening the "U", which is a fixed bar structure.

Update soon... ?

Dont WASTE YOUR MONEY!!!
Will not stay in place, a ten pound box will make it flip up and release yor cargo all over the bed the feet at the bottom are poorly aligned not worth 54 dollars, cheaply made. I spent 12 dollars at the lumber yard and made a custom cargo fence this works 10 times better. I you have to have something like this spend the money on a good bed extender forget this junk it's going back!!!

Great for separating your bed.
Great for separating your bed. You and your spouse will be able to sleep in peace. No, not that kind of bed! A truck bed, silly...

This fit in by Chevy C10 stepside just barely (bed width about 48 1/2") but I'm glad it did. I have it installed by the tailgate so it will keep grocery bags upright and secure while driving home. It won't damage your bed as long as you install it properly, it has two rubber skids on each end that should wedge in nicely. It was simple to assemble, and has a very nice looking spotted grey metal finish. The pouch will hold small items, but they may come out if you hit a big bump.

This is a great solution to organizing your truck bed better!

EDIT Apr 8, 2010: The rubber end skids fell off and got lost. Now I can't use it anymore else I'll scratch my bed paint. I will have to make a custom rubber pad of some sort before I use it again. If you get this product, make sure the skids are glued on good and tight.

convenience
I love not having to chase things up and down the truck bed. Nothing gets banged up or damaged. It was fairly easy to install and have options for changing placement in the bed.

Great product
This is a great product, and it works the way it should.
Easy to move to a different location in the bed of your truck for different loads you are carrying.

Good
Works pretty well; a little difficult to screw and unscrew for placement or removal; still has some slippage when placing heavy groceries behind the barrier.
