Moisture build up at bottom of lower dome for the Spectra III or IV series outdoor housings.


When the Spectra pendent dome is installed, it will have a open cable entry pipe along the top of the back box. The entry if not sealed properly will allow moisture to come down inside of the dome.

When the Spectra pendent dome is installed, It is recommended to install ducking compound into the pipe to seal the cable entry point and prevent moisture intrusion.
