Question: does this work as an outfeede support on the 7491rs ?
Document: These things are great. They are firm enough to support the work when ripping or cross cutting long stock. They do what they are supposed to do and are a must have if you own the dewalt 744.
I bought these with the saw, but they are to short to support much. I don't think they are worth the price. I think that a seperate outfeed roller would work better.
I have owned the side and outfeed supports for over 5 years. While they are a great addition to expanding the work surface, they fall short of the performance of an actual outfeed table.The problem with adding an outfeed table to a Dewalt DW744 is that the rear bar that accommodates the gear fence mechanism must be free to move when adjusting the fence which eliminates it as a fastening point for an outfeed table.One solution is to attach a wood block to the Dewalt rear outfeed support.
How to make an excellent saw even better? Add the side and rear extensions, especially if you work a lot by yourself. O'kay, so they're kind of steep -- still make you work smarter and safer. Faster too -- so they ought to pay for themselves pretty quick.
These work great however the dude feed falls out when tilting saw to roll around. If this had a wing but set screw on either one to lock into place it would be perfect. I put masking tape around the tubes to make a tighter fit and lock better into place.
These work great. I don't know why others complain about them being low or sagging. They are fully adjustable and you can set them even with your table top. They are so simple I don't know how anyone could have trouble figuring this out. My only complaint is they crowd the storage area on the side of your DW744 just a bit (where you keep the spare blade and wrenches). Not a big deal though.
Quality product, and a great upgrade for Dewalt's portable table saw. It does add a bunch of weight to the saw decreasing its ease of portability, but we are all strong backed carpenters, right?! Anyway, the feed supports were very easy to install (took about twenty minutes) and work very well when working with large lumber. Worth every penny...
The dewalt support on the table saw is perfect for those who have the need to cut all 4x8 sheets or needing that extra support making miter cuts.
This DEWALT DW7441 Side and Outfeed Support  is really well made with heavy material. It truly helps when cutting materialon projects. Easily installed
The Dewalt DW7441 side and outfeed support works great.Now I can cut full sheets of plywood with ease.I would recommend this to everyone.
