This do-it-yourself kit includes the J-hook, female attachment clip, and all the hardware and tools needed to replace the attachment system on your FlightCrew2, FlightCrew3, FlightCrew4, or FlightCrew5 Rollaboard.
Could you use this kit to retrofit a non-Travelpro rollaboard? Sure, but we make no guarantees that this system will work with your bag as it will require your bag to have adequate frame material and drilling holes in the frame.
