Note: This post has been moved from Festool Jigs & Enhancement section to comply with FOG rules. Look there for the details of RSU2.
I made couple extra sets of the RSU2. PM me if interested. You can have it for $120 shipped in USA. This is what you’ll receive:

There are few things to be aware of using RSU2:
1. Spline that fits into the guide rail slot is approximately 8.6 mm wide. Guide rail slots vary 8.4 – 8.6 mm from rail to rail. You may need to sand or shave it with a plane to fit yours.
2. Splines on the support blocks fit into MFT slots. For use with 8020 40 or 15 series extrusions they need to be sanded or shaved to 8.3 mm. I found that plane works best for the task. Only the top part needs modification, the base should remain 8.6 mm to fit tightly into the aluminum block. It shouldn't be difficult to adapt to other t-slot types or make new splines altogether.

3. When using RSU2, first, fully insert the plastic spline of the front support, adjust the height and clamp. Only then adjust the back hinge height and clamp. This sequence is needed because hinge rotates when not clamped.

4. Make sure that M8 screws securing horizontal bar and hinge to the rods are tight. You don’t want them to rotate while the rod is locked.
5. For use on MFT3 the rear guide rail overhang ("L" on the picture) should be no more than about 55 mm if you want the rail to stand vertically on its own and not interfere with the support block. If you use the top t-slot of 4080 series type extrusion (like I do) than L should be less (~35 mm). If you use bottom t-slot, than the overhang could be about 70 mm. Either way there is enough room to cut across the entire MDF part of the bench even with TS75. I actually prefer long front and short rear overhang, so the saw is completely plunged before the cut.
