Breakaway Protection
The marker arm is attached to the marker body with a 3/8"
shear bolt as shown back in Figure 3-23. If excessive force
is applied to the marker during operation, the shear bolt
will break, allowing the marker arm to swing away rather
than cause damage to the marker.
NOTE: The breakaway bolt is a 3/8-16 x 2" long grade
2 (GP# 802-266C). It is identified as a grade 2 by hav-
ing no marks on the head. If is breaks, it must be re-
placed by an equivalent grade 2 bolt to prevent marker
damage.
