Question on Cages
Rear braces must
be of the same diameter and wall thickness as the roll bar and
intersect with the roll bar at a point not more than 5 inches from
the top of the roll bar. Crossbar and rear braces must be welded
to main hoop. Sidebar must be included on driver’s side and must
pass the driver at a point midway between the shoulder and
elbow. Swing-out sidebar permitted. All roll bars must have in
their construction a cross bar for seat bracing and as the
shoulder harness attachment point; cross bar must be installed
no more than 4 inches below, and not above, the driver’s
shoulders or to side bar. All vehicles with OEM frame must have
roll bar welded or bolted to frame; installation of frame
connectors on unibody cars does not constitute a frame;
therefore it is not necessary to have the roll bar attached to the
frame.
