Sta-Kon F10721UFR – Frequently Asked Questions
1) Can I use this copper ring terminal on aluminum conductor?
No. The F10721UFR is a copper terminal intended for copper conductor at 4 AWG. For aluminum or dual-rated runs you need a lug specifically marked AL9CU or AL rated, not a plain copper tubular terminal.
2) What does the 45 degree reverse bend on this ring terminal actually do for me?
The tongue is offset at 45 degrees away from the barrel instead of running straight out, so the ring lands flat on a pad that sits at an angle to the cable run. It's what you reach for in tight panels, breaker lugs and busbar stacks where a flag or straight terminal would force you to bend the 4 AWG conductor hard to get the ring square on the stud.
3) Is this a non-insulated terminal, and do I need to add my own insulation?
It's a bare copper tubular ring terminal with no insulating sleeve. The crimp barrel and tongue are exposed, so in any application where the connection needs covering you add heat shrink or a boot yourself. Non-insulated also means you can inspect the crimp and use it where sleeve material would not survive the heat.
4) Does this terminal need a crimp tool or can it be soldered?
It's a tubular barrel terminal, so it's installed with a crimper sized for 4 AWG copper lugs, typically a hydraulic or heavy mechanical crimper with the matching die. Pliers or a light hand tool will not produce a sound crimp at this conductor size.
5) Where is the Sta-Kon F10721UFR made?
Country of origin is Mexico. That is the detail procurement teams with domestic-content or origin-reporting requirements usually need in writing before a PO goes out.
