They’re track clamps. The head of the MATCHFIT Dovetail Clamps are forged into a dovetail shape, compatible with any standard ½”–14º dovetail router bit. It moves through the track created by a router bit instead of an expensive metal t-track.

Not really.  Dog holes only allow clamps to go through the material with the head sticking out of the bottom.  Dog holes confine clamps to fixed locations, which aren’t always where you need them.  Dovetail Clamps can be positioned anywhere in a dovetail track, inside the material and out of the way.

Only if you value your time.  Standard dovetail router bits cut to a sharp point at the top of the groove, which requires a decent amount of sanding after the track is routed.  Our router bit incorporates a 1/16” roundover to automatically smooth out the top of the track in a single pass.  Less time sanding means more time building.

When tightening anything inside of a t-slot, the pressure is applied perpendicular to the material surface, which may weaken the integrity of the track.  If a t-slot is cut into plywood, all of the force is concentrated on the small flange at the bottom, causing the plywood to delaminate. With a dovetail profile, the clamping force is distributed evenly along the entire wall of the track for an overall stronger hold.

The clamps will not, the hardware will, but that’s kind of missing the point.  The MATCHFIT system was designed to be compatible with a standard router bit profile, so that users wouldn’t actually need metal tracks.  However, some users have been known to file or grind about .005” off of the wide part of the clamp’s elbow and use them in their Festool track.  Our advice is to use Festool clamps with Festool tracks, and use Dovetail Clamps for everything else.

When you tighten the Dovetail Hardware into a plywood or MDF groove, the 14 degree dovetail profile wedges the plastic head of the hardware in place in the groove.

This "locks" the hardware in place so it cannot move side to side within the dovetail groove. So you can wedge a Track Screw in place, loosen the knob, and turn a cam clamp to secure stock in ways that T-Track hardware cannot.

When you are done, just press the Track Screw or Track Nut back down into the groove to 'snap' it loose and slide it to your next task.

Good quality plywood or MDF work just fine for the MatchFit Dovetail System. Because the clamp pressure is normally directly over the clamp head in the groove, the groove is supported and the board does not tear out. There is a video showing the process here: https://youtu.be/oHtOey0-97U
