Can anyone tell me what the holes are in the front of the D26204 router? You can see them facing you in this photo. I thought at first they were just some sort of alternative holes for the fence, but they aren’t. They are smaller diameter ( less than 8mm ) and also the screw holes above them ( presumably to secure the rods that fit in the holes ) are also not the normal DeWalt wing bolt size.
Usually they are for a fence/guide for straight passes. The rods slide into those holes. The screws up top lock the rods in place to the fence, so the guide doesn’t move.

The rods won’t fit. The rods are 8mm and those holes are less. Not only that but the screw holes on top are a non-standard size too, the normal DeWalt wing bolts won’t fit.
And that is the rods that came with it?
Maybe the Universal Edge Guide with Dust Collection. It comes with multiple rod sizes. 
I measured them yesterday. They holes are 7mm ( I can’t tell whether it is 9/32 or 19/64 but it’s more than 7mm and its less than 8mm so I am assuming its an American measurement. )The supplied rods are 8mm so they don’t fit. I believe the rods with the universal are 8mm and 10mm. Also the spacing between the holes is 6cm, which is completely non standard too. At least an inch too small for any guide or fence. And as I keep saying, the standard DeWalt wing bolts do not fit. The diameter seems correct but the thread is different. They are not metric so once again I am assuming they are an American size. I have tried various fences, guides, including the rail adapter and nothing fits.
I just don’t get it. That is weird why they wouldn’t fit when they all came with the tool. Let me see if I can find anything out.
(DWS5031) DEWALT Router TrackSaw Guide Adapter uses the included adapter that is marked for 690 & 890 series routers. Adapter kit works with multiple brands of routers and tracks.
Ah! The 5031 has changed!! The new version has a special bracket for the D26204 router…. It now fits on the other side of the router to the standard rail fittings using standard wing bolts. So the old fitting on the router is not used for anything unless you happen to have an older version of the 5031. Great. My curiosity is answered. Thanks guys!!
Holes appear to be the same on those found on the Porter Cable plunge bases. Any of the Microfence attachments for cutting circles should fit.
Unfortunately Porter Cable products aren’t really available where I am. Otherwise I would probably buy the circle cutting gear.
My guess here is the 5031 is probably still the same in the US where Porter Cable are available, but not here in the UK since they aren’t.
