Input:
Question: Is the VR -861 rack a pair of folding J cradles . No where is the pair indicated in the description
Document: Works just as well as Thule or Yakima Kayak holders, and cost considerably less. Quick, easy install. Mounted it on round Yakima bars. They will rotate slightly on the bar if you apply enough force, but it was not an issue. Folding is easy... just give a knob on each side of the carrier a 1/4 turn to lock or unlock.
Answer: no
