Microjig makes some great products. I use their safety products consistently on my table saw and router table. Dust is always a health and cleanliness issue when working wood. My Jet JPS table saw has dust collection capability, and has a 4" Delta dust collector on it.

The issue that the Microjig magnetic dust cover addresses is the large gap in the cabinet where the height adjustment resides. This large gap draws in air to the dust collector, but not significant dust. It this reduces the vacuum at the blade protrusion. This is particularly true with zero-clearance inserts.

The magnetic dust cover fits around the shaft of the height adjustment wheel, attempting to seal the gap below the wheel that shoes the tilt angle. In my case, the tilt angle is indicated with a protruding pointer. Because it protrudes beyond the steel side surface, the magnetic cover is bulged there, creating a modest opening for air entry. Not as large as without it, so it does do most of its job.

Construction is fully adequate, with a fairly thick magnetic sheet. (Haven't measured the thickness, but greater than magnetic bumper stickers.) You must make a cut (scissors) to put it around the shaft, as the typical adjustment wheel is far larger than the shaft hole in the dust cover. NBD, as the cut can be situated over the steel side, leaking no air.

Bottom line: this is a fairly inexpensive way of helping dust collection.

I wa skeptical that this would work but at the low cost what the heck. I gave one a try on my big Jet brand cabinet saw and yup. It works! A noticeable improvement in dust collection in the base cabinet. I could do without the billboard style advertising on it though. But it is an out of the way place so I'm used to it already.

Easy to trim and install. One star off for being an advertisement. As others have done, I'll spray paint it to match the saw cabinet.

I installed a new Saw Stop table saw, contractors model. I was very disappointed with the dust collection. Much more saw dust was escaping than I was use to. There is a very large clearance cutout in the front panel of the saw. I slapped this magnetic dust cover to the front panel of the saw and the dust collection improved a great deal. This magnetic dust cover covers the gap in the front metal cover of the saw. Simple. This item should be standard for every SawStop table saw.
