POWERTEC 71609-P4 3" T-Track Intersection Kit with Predrilled Mounting Holes, 4 Sets, Universal T-Track Accessories for Woodworking Jigs and Fixtures

I've used several packages of these now: well machined and work perfectly.

Ordered 4 sets. Got one. Ad clearly says 4 sets. Package clearly says 1 set.

Awesome product

Dude, this POWERTEC T-Track Intersection Kit is a game changer for jigs and fixtures! Forget tricky measuring and drilling – the pre-drilled holes make assembly super easy. Plus, the tracks cross over so you can move your clamps and stuff in all sorts of directions. No more wrestling with awkward setups for different projects. It's built well and affordable, so totally worth it. Just sayin', these are just the intersection pieces, not the whole track system.

I used 12 of these intersections on an assembly table in my wood shop. All of them are accurately made so they line up perfectly with my other sections of T-Track. Excellent value for the price.
