Slotted 10 BWG Sign Support on CMB

Report Number(s): 0-6646-1, 466462-4

Description: The installation for test 466462-4 uses the same post mounting assembly incorporated in test 46646-1 except for the sign post. The sign post is 10 BWG with four symmetrical 3-inch long slots placed around the post just above the schedule 40 collar. There is a bushing between the post and the collar on the ¾-inch bolt that goes though the sign post and the collar. This bushing helps reduce the post from vibrating within the collar
