Sta-Kon RB2253M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB2253M fork terminal take?
The RB2253M is sized for 18 to 14 AWG stranded copper conductor. Blue insulation is the standard color code for that range, so a blue barrel on the bench is the quick visual check that you have the 16/14 range part and not the red 22-16 or yellow 12-10. Outside 18-14 the crimp will not hold reliably, so step to the next barrel size rather than over-crimping.
2) Will the RB2253M fit a No. 10 screw terminal block?
Yes. The fork tongue is sized for a #10 stud or screw, which covers most control panel terminal strips, motor starters, and contactor terminals using 10-32 hardware. The locking tongue means the fork grips the screw shank and will not back off the stud under vibration the way a plain spade will.
3) Should I use a locking fork terminal or a ring terminal for panel wiring?
Use the locking fork when you need to pull a conductor out without fully removing the screw, which is most control panel and terminal strip work. The RB2253M's locking tongue addresses the usual objection to forks, that they can slip off a loosened screw, by capturing the screw shank. Choose a ring terminal instead where a code or spec requires a fully captive connection, such as a grounding stud or a vibration-heavy motor connection.
4) Is the insulation on this Sta-Kon fork terminal nylon or vinyl?
Nylon, with a Mylar-lined barrel. Nylon holds up better than vinyl to heat and to the abrasion of pulling harnesses through a panel, and the Mylar liner backs the insulation sleeve so the crimp does not split it. That is the reason to pick this over a cheaper vinyl insulated fork in a hot enclosure or a motor control center.
5) What conductor material is the RB2253M barrel, and can I use it on aluminum wire?
The barrel is copper, so it is for copper conductor only. Crimping copper-bodied terminals onto aluminum wire creates a dissimilar-metal joint that corrodes and loosens; aluminum runs need an AL/CU rated connector instead.
6) Is the Sta-Kon RB2253M made in the USA?
Country of origin is the United States. That matters on government, military, and institutional jobs carrying Buy American or domestic preference language, where a foreign-made terminal gets the submittal rejected.
7) What is the exact part number to order this blue locking fork terminal?
Order Sta-Kon RB2253M. One part number covers the configuration: nylon insulated locking fork, 18-14 AWG, #10 stud, blue, Mylar lined. There are no finish or size options to specify behind it.
