Customer Rating: - The other great addition to a great saw!
I had the saw for about a year when I bought this extension and the rear one.

You may have read this same review for the side extension but here goes anyway.

The saw has tapped holes ready for Both of them, they mount independently and work very well.

The illustration shows them both in a with rails in a vertical position which makes hard for a left handed person to visualize how they support the work. Of course for the less challenged you could automatically tell that they were mount to the underside of the table and slide out for use. My brain was trying to see how these legs could support it from the floor...duh!

Anyway, if you work alone (which you shouldn't of course!!!) they are a godsend.

Customer Rating: - It works great for me
I have no idea about what these other people are writing about, I just installed the rear extension right out of the box and it not only fit great, , but it worked wonderfully.

Customer Rating: - Must have!
This is a must have accessory for your Bosch table saw; easy to install and use.

Customer Rating: - It rubs on the Bosch 4100 Saw, and hits the digital read out
Excellent idea, but it rubs on my new 4100 Bosch Saw, and is scratching it pretty good. Also, when the support is closed, it will hit the digitial carriage (read out display). If you want to dock it (magnetically secure) the display you have to pull out the support a bit. Again, I like the idea, but it needs a lttle refinement for the fit on the actual table saw.
