The Park Tool 180 Lock Block Assembly is standard issue on all of Park's professional lever repair stands. This handy piece allows you to rotate the adjustable linkage clamp in the stand to accommodate a wide variety of tube sized and bike styles. The Park Lock Block Assemble will work with the Park PRS-2, the PRS-3, the PRS-4, and any PRS-5 that was built before 1996.
