Roll bar that is designed to fit under the factory hard top that comes on the ever popular china JK 2dr body. It mounts using the four holes that the hard top leaves unused when installed. I've also designed it accept either the 3mm( http://pekabe.com/store2/standing-rigging/shackle-3mm/

) shackles to use as tie downs for your spare tire or other scale accessories.
