• 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.
