This roll bar is manufactured from large 3" (76mm) diameter black nylon coated steel tubing. It consists of a single hoop behind the cab of the vehicle that bolts through the top of your bed rail.
From this single hoop two stays come back and again fixes to the bed rail allowing full use/load capacity of the bed. If you wish to mount spot lights to the roll bar then that is the option of the light mounting brackets. Roll Bars are sometimes referred to as pick up sports bars, pick up styling bars, pick up roller bars.
