The QCW uses a 1/4-20 track. Rockler clamps do not work with it (and we don’t recommended using high clamps like this for CNC uses, 9/10 you’ll break a bit crashing into them with the router 
)
Our qcw t track is designed for use with our Oops clamps: https://www.onefinitycnc.com/product-page/oops-clamps-for-t-track-large-set?srsltid=AfmBOopyaAEaN_DkmmGM2tUUk-cZvijMQ9IojUJ8h0AEbn12cq6dcBVW
A standard 1/4"-20 bolt head fits in the t track.
