I ordered the CR-4 by Leecraft to fit my Craftsman 21833, which is not the best table saw in the world in terms of accuracy. In order to rip red oak trim pieces .25in thick, I needed a zero clearance insert and rip jig.

This table insert is solidly built (looks like it is machined-milled for accuracy) out of some high density synthetic material. It is about .75in thick, with the top face being laminated in a melamine material (NOT red as pictured, but marbled peach color); very smooth for work to slide over.

The underside has a portion of pre-cut so that you are not raising the table saw blade through .75in of material; I would say about 3/8" of material is what the blade has to work through. Behind that is a pocket milled out for the knife (if you have one); again the material you have to cut through is not the full thickness but rather 3/8". I do not use my table saw knife and have no idea how hard it is to cut through accurately.

There is no metal contact for the insert to be held in by the magnet in the table; there is a set screw (phillips screw) in the back of insert to take up any blade-parallel movement.It works quite effectively.

When the blade moves through the material, there is no rip out; go slow to be careful. I had my fence over a portion of the insert during this process just to make sure that there would be no up-lift in the piece.

Very rigid material, no walking or tipping, very sturdy, material slides over it smoothly. Great quality product.

By far the single best addition to my Craftsman table saw, the fit on this is perfect for the saw. It's easy to adjust so there's no play with the set screw in the rear and very simple to level.

I'd give it 5 stars except for the way in which the riving knife and anti-kickback devices come through. The outlines they have on this are not quite correct and it took a drill press and a chisel to get the holes right. That's not too bad because I have purchased 4 of these, one for the standard kerf blade, another for a thin kerf, #3 for my dado and #4 for a Freud box joint cutting blade.

Not only would I recommend these but I plan on buy several more just to have on hand. I'd like one for 45 degree angle cuts.

I purchased three of the CR-4 inserts for my Craftsman 21833 table saw.
Overall I'm pleased with the product. It is exciting to see the zero
clearance face. I would recommend these and plan on purchasing a couple
of more even though I can make my own. The insert fit perfect and the
tension screw was the key -- an added bonus.

I do take issue with multiple materials being used to make the CR-4. It
would be much better as a solid piece of high density phenolic laminate.
The result of being more than one piece is that the top material
cracks/chips easily.

As in my case, the melamine face cracked and I used hot glue to somewhat
seal it. While it is still usable, it's disturbing to pay $35.00 a piece
and have a problem with the face chipping before ever being used. The
melamine face chips / breaks away way to easy when cutting the riving knife
hole, even when using a drill press to get the corner holes perfect.

Also, the e-mail provided for comments in the package "ronleecraft@gmail.com" does not work.

Great product. Sure I can make my own inserts but I wanted something more substantial (safer)
for when I use a dado. Worth every penny.

Fits properly and cut cleanly.

Only gripe with it is that I have to redo the leveling screws when I switch between this and the stock insert. I'm not going to deduct a star for that because that's probably to be expected, it's just an annoyance.

It also throws up a lot of sawdust, but I assume all zero-clearance inserts do that.

Bought this for a Craftsman 21833 table saw. The insert is narrower than the stock insert and is only sorta-tight when the "adjusting screw" is carefully set. I feel like this is really a improperly machined insert. Should be a similar width as the stock insert.

Stock insert is 4.085" wide and this Leecraft insert is 4.055" wide.

Sending this back!

Update 4/13/2015: OK, so I purchased the Sears Craftsman zero insert clearance and it fits PERFECTO!!! I can't really vouch for the service life of the Craftsman insert as it's made from plastic. I would urge Leecraft to up their game and fix their ill fitting (but VERY nicely made) insert.

This zero clearance plate works wonderfully with my craftsman hybrid table saw. The only problem was when I drilled out the holes for my MicroJig splitters. The bottom of the plate allready has a recess for your riving knife assembly built in, so if you opt not to use the built in riving knife (which is also a pain to cut the groove for), the plate is about 1/8" inch thick at the point the splitters will insert into the zero clearance insert, this doesn't support the splitters very well and they wobble a bit more than I would like. If the top was at least 3/8" thick at that paint, it would be fine.
