Conduit Installation Details
GAI-Tronics recommends installing telephone lines in conduit to protect against accidental damage and
vandalism. To prevent moisture from entering the enclosure:
Conduit should enter the enclosure from the bottom whenever possible.
Sealed fittings should be installed at all cable entry points.
Silicone sealant or equivalent should be applied around and inside all conduit entries to prevent
moisture ingress.
Refer to the examples below for the recommended conduit installation details:
