Create a protected cable-entry transition at a 3/4 in NPT threaded opening with this plastic waterproof joint. The UNITED DIGITAL TR-A01 is intended for surveillance installations where cable routing reaches an outdoor enclosure, camera accessory, or other threaded connection point that calls for a 3/4 in NPT fitting. Its waterproof-joint form factor addresses the connection point rather than adding camera, recording, or network functions. TR-A01-IN identifies the orderable version of the TR-A01 model. Match the 3/4 in NPT thread requirement before selecting the joint, particularly when replacing a fitting or completing a cable path through a threaded enclosure entry. Plastic construction makes this a purpose-built fitting for the cable-entry portion of an installation. It is not a camera mount, an imaging device, or a powered network accessory. Use the joint where the installation requires a waterproof transition around a threaded cable route and where the mechanical interface is 3/4 in NPT. The defining characteristics of this configuration are its 3/4 in NPT size, plastic material, and waterproof-joint function. These details help separate it from fittings with different thread sizes, materials, or connection purposes. Plan the associated enclosure opening and cable-routing method around the required threaded interface.
