• Bayonet Coupling Style: The jack has a pair of guide posts that accommodate the plug’s
lockdown slots. This lockdown design provides secure assembly without over-tightening the
connection.
• Threaded Coupling Style: The jack features external threads. The plug shell features internal
threads, and has either a knurled outer surface to permit hand-tightening of the connection,
or hex flats to accommodate torqued installation.
Connection Instructions:
• Bayonet Coupling Connections: Use the plug slots to guide, then slide the plug onto the jack
posts. Then, turn the plug clockwise until the jack posts are fully seated within the plug slot.
• Threaded Coupling Connections: Engage the plug onto the jack threads, and then turn the
plug clockwise until it is fully threaded onto the jack. Do not over-tighten the connection.
