A-FRAME HOLE POSITION
IMPORTANT! Before assembling headgear to
A-frame, measure the vehicle mount height to
confi rm whether standard receivers or tall receivers
are required, and which A-frame holes to use for
installation. (If the truck is not available, use the
middle position. Make any adjustments later.)
Before measuring the vehicle mount height, the mount
must be installed on the vehicle, ballast (if required)
must be installed, and the vehicle must be parked on a
level surface.
1. Measure the distance "d" from the ground to the
center of the hole in the vehicle mount. Measure
the distance on both sides of the vehicle and
determine average value for "d."
