Question:
Hello etrailer Staff, Vehicle: 2020 4Runner. Is the Inno Box 320 or Inno Wedge 660 compatible with the Thule Cargo Box Kit TH36PS? And in turn, can the Thule Cargo Box Kit TH36PS be mounted on a Prinsu Pro rack? I have garage clearance requirements and only need a little more storage space. Thanks so much for your assistance.

Hey Matt, the Inno Wedge 320 part # IN94FR and the 660 # INBRM660BK both can attach to the Thule Caprock Adapter Kit part # TH36PS as long as you use the Inno T-channel adapter part # INBRP12.
While the part # TH36PS was designed to attach to the CapRock platform rack it would basically fit any platform that has top channels built into it which the Prinsu Pro would have.
