2. Secure the cable with a cable tie and plastic anchor every 18 to
24 inches along the pipe crown (when necessary) from the ring

anchors based on the structure of the pipe, install ¼-inch x 2
¼-inch bolts instead.

manhole safety hazard or increase the potential for sensor or
monitor damage. If plastic anchors will not serve as adequate
anchors based on the structure of the manhole wall, install ¼-
inch x 2 ¼-inch bolts instead.
