Sta-Kon RK9721 – Frequently Asked Questions
1) What wire size does the Sta-Kon RK9721 ring terminal take?
The RK9721 is sized for 2/0 AWG conductor. That is a heavy power cable size, so it belongs on feeder, battery, or panel-feed terminations, not on control or branch-circuit wiring. If you are landing 14 to 10 AWG on a lug, this is the wrong terminal.
2) Is the Sta-Kon RK9721 terminal insulated, and what is the insulation made of?
It is a nylon insulated ring terminal. Nylon sleeves hold up better to abrasion and crush during crimping than vinyl, which is why they get specified for larger conductors landing in tight gutters.
3) Is a ring terminal or a fork terminal better for a 2/0 cable landing on a stud?
Use the ring. A ring tongue, like the RK9721, captures the stud completely, so the connection cannot back off the screw if the nut loosens. Fork or spade tongues slide off under vibration and are only used where the terminal has to be removed often without pulling the nut all the way. On a 2/0 power termination, go with the closed ring.
4) Do I need a special crimper for the Sta-Kon RK9721?
Yes. A 2/0 terminal is well past the range of a hand-squeeze crimper for insulated terminals. Terminals this size require a heavy-duty hydraulic or ratcheting lug crimper with the correct die for the barrel. Crimping with pliers or an undersized tool will not produce a compliant termination.
5) How do I order the exact Sta-Kon ring terminal for 2/0 wire?
Order by manufacturer part number RK9721 from Sta-Kon. It is a single configuration, 2/0 nylon insulated ring terminal, so there is no finish, stud size, or length option to specify separately.
