The Or-Fab Sport Cage hugs the contours of the interior taking up minimal space and can be used with factory or aftermarket cloth or hard tops. Installation strengthens the vehicle's chassis. This design is made from 1-3/4" diameter .120-wall tubing and does not interfere with air conditioning vents or window cranks. Driver and passenger grab handles are built into the cage and 2 front streamer bars are included for additional strength and rigidity without taking up lots of head room. Mounting brackets made from 1/2" thick steel bolt along the vehicle's door pinch-weld seam. This cage is designed to integrate with Or-Fab's floor mount kit 82301 in order to securely connect the cage with the Jeep's floor channel reinforcement. Floor mounts sold separately. Proudly made in the USA.
