This is the replacement J-hook for FlightCrew2, FlightCrew3, FlightCrew4, or FlightCrew5 Rollaboards.
Most FlightCrew line rollaboards come with a J-hook attachment, so there is no need to purchase this item unless you want a replacement or want an extra J-hook.
Bag attachment is shown in the descriptive pictures. If your attachment does not look like that, then this strap will NOT fit your bag. Not compatible with Travelpro Slim Rollaboards.
