This former Standard Plan (J-1c) was developed many years ago to address the need for breakaway designs for light standards.
The adapter plate allows an older four bolt fixed base light standard to be converted into an acceptable slip base unit. A breakaway feature, such as the slip base, is required if the light standard is within the Clear Zone. There is no specific bid item for the use of the adapter plate and will need to be developed by the user of this plan.
