The extension is a great add to the Bosch 4000 saw. It installs easily and operates smoothly. The extension is all steel construction and uses aluminum brackets to attach to the underside of the table. The extra support is great for crosscutting long boards and definitely saves time not having to setup sawhorses or roller supports.

A tip to the perfectionist group - the extension does have a minor amount of slop/droop (about 1/16" in my case) when extended. I remedied the problem with one 1/4" internal tooth lock washer placed between the bracket and the body of the saw on both the front and rear. Torque it down to flatten the washer as much as possible being careful not to strip the saw housing. Placing the washer on the inside bolt of the two keeps the extension fairly level throughout the span of the extension.

Length:: 3:58 Mins

There seem to be plenty of conflicting reviews on both the left side extension and the outfeed extension, and I've made this video to clear them up. Issues cleared up:
- The front bar for the left side extension is short enough to not hit the red lever for the right side extension.
- Both left side extension and outfeed extension come with a stop knob for securing the extensions either open or closed.
- Both extensions sag just a little, which I fixed by placing a washer (approx 0.043 in thick) between the brace and the tablesaw for the _back_ bolt on each bracket. This modification brought it very close to level, for just over $2 in washers at my local big box hardware store.

I do say a few odd words here and there in the video (quarters when I meant washers, etc.) But I'm sure you can figure it out.

Overall review: These were what I expected, fit my 4100 series Bosch worksite table saw, and were easy to install following the included instructions.

My left side support arrived with the threads missing from one of the support rods. It appears to have been misformed during the machining process. I had to contact Amazon for a replacement, which they promptly sent out at their expense. They also paid for return shipment of the defective unit.

Others have noted that they shimmed the inside mount slightly to compensate for droop. There is a bit of adjustment in the support arm itself- allowing you to adjust it up by a 16th or so.

Here's a tip: If you purchase the rear support as well, you'll notice that the aluminum support brackets are tapped and include a 'set screw' which is useful to lock the position of the support both for transport, and during use. For some reason, the left support does not include this feature. I picked up a similar thumb screw/ set screw from my local hardware store and added the same functionality to my left side support. Just drill a hole in the thickest part of the aluminum support, and tap threads into it. Now screw in your thumbscrew. No more accidental openings during transport.

This side extension is very worth the money. It's easy to install and works smoothly. It does droop a bit so may need some washers on the far bolts to level it out.
If you have the Bosch 4000, you should have this side extension.

If you own the saw, get this. Improves stability when cutting long or wide pieces. Installs in minutes and stores flush to table.

I am impressed with my recent purchase of the BOSCH TS1003 Left side support extention for my table saw. From the intial ordering to the installation, the whole process went very smooth. It attached with no problemsby screwing to the underside of the table very securely, increasing the over table width to over 50 inches.

You need this left side support for your Bosch 4000-9 Jobsite Table Saw. Installation was very easy except I spent a lot of time trying to figure out what I did wrong. I found out that the right side extension release handle, that came with the saw, wouldn't let the left extension sliding rod go fully into the closed position unless the right side extension handle is pulled up an inch or so. I like the left extension so I can live with the handle sticking out an inch and the lock still works. I can't believe Bosch let that design flaw go. I guess they knew we would still like the extension.

The Left Side Support extension is everything it is supposed to be. Solid, heavy, a good general fit, and with thoughful design features which make it a 'natural'accessory. Marginally off horizontal at full extension (slightly below table level), I temporarily compensated with (gulp) a 1/4" Duct Tape longitudional strip as a 'shim' on the outer arm top (nice and easy to instal, stays put, and is 'slippery'). I'll get around to a better solution with a washer or two on the mount bracket (maybe). I think this Support Extension is just about a must have, and is well enough constructed to be worth the price paid.

Bought this for my new Bosch 4100 table saw (new model released several weeks ago). Manual said that this TS1003 is compatible but after installing...or trying, found that it does *not* fit the 4100. Will be calling Bosch to see if they have a replacement part that has been redesigned to fit. Strange thing is that even the instruction sheet that shipped with the TS1003 said that it fits both 4000 and 4100 model saws.

I recently installed this left side support on my Bosch 4000 Jobsite Table Saw. Installation was a breeze and it is an essential add-on. The only problem is that the new right side extension release/lock mechanism installed on the saw, when in the locked position, prevents the left extension from going fully into the closed position. It is necessary to move the orange lever to about a 30 degree position to fully close the left extension.
