Hook Aerial Cable 1

Hook Aerial Cable 1

The Aerial Cable Hook No. 1 (CN 2991) is a heavy-duty steel support hook designed for securely mounting overhead telecoms cables in fixed network and aerial deployment environments. Manufactured to British Telecom specifications, this hook provides exceptional structural strength, precise dimensional accuracy and a durable protective nylon coating suitable for long-term outdoor use.

Engineered from MS SPEC BS 4360/43A steel and finished with Rilsan nylon coating enhanced with molybdenum disulphide, it ensures outstanding weather resistance, reduced friction and extended operational life. With accurately machined fixing holes, controlled tolerances and a reinforced top plate, this hook remains a trusted component for traditional Openreach-style aerial cabling infrastructure.
