Telephone Junction Boxes
Telephone junction boxes are used to split, join, and distribute communication signals at key connection points within low-voltage networks. These enclosures provide an organized and protected location for terminal blocks or punch-down blocks, allowing multiple telephone lines or communication cables to be securely terminated. Commonly used in commercial, industrial, and utility applications, telephone junction boxes help ensure reliable signal distribution and long-term network performance.
Available in sizes ranging from approximately 10 inches to 48 inches in height, telephone junction boxes are designed for both indoor and outdoor installations. They are manufactured from durable materials such as plastic and metal to withstand environmental challenges, including moisture, dust, humidity, and wide temperature variations. Many models feature weather-resistant gaskets and tamper-resistant locking mechanisms to protect internal connections from unauthorized access and environmental exposure.
Telephone junction boxes are typically rated NEMA 1 for indoor, dry locations or NEMA 3R for outdoor environments where protection against rain and sleet is required. While primarily intended for telephone wiring, these enclosures may also be suitable for other low-voltage communication services such as cable television or internet cabling, depending on local codes and application requirements.
