Sta-Kon RB2237M – Frequently Asked Questions
1) What wire gauge range does the Sta-Kon RB2237M fork terminal take?
The RB2237M accepts 18 to 14 AWG stranded copper wire. The blue insulation is the standard color code for that 16-14 AWG band, so if you are crimping 22-18 AWG (red) or 12-10 AWG (yellow) conductors, this is the wrong barrel size and the crimp will not hold.
2) Will this fork terminal fit a No. 8 screw terminal block?
Yes. The RB2237M is sized for a No. 8 stud or screw, so it slides onto a loosened #8 terminal screw without removing it. On a #6 screw the tongue opening will be loose and can shift under vibration; on a #10 stud it will not seat.
3) Is the Sta-Kon RB2237M rated for 600 volt control wiring?
It carries a 600 V rating and is UL recognized under file E9809, which covers the typical 120/240 V and 480 V control and power circuits in panels, motor starters, and lighting gear.
4) What makes a locking fork terminal different from a plain spade or a ring terminal?
A locking fork has turned-up tangs at the tips of the tongue that catch under the screw head, so it resists backing out under vibration the way a plain spade can. Unlike a ring terminal, you can still install or remove it without taking the screw all the way out, which is the reason panel builders and control technicians use them on dense terminal strips. If your spec or inspector requires a fully captive connection, use a ring tongue instead.
5) What is the barrel and insulation made of on this blue fork terminal?
The RB2237M has a copper barrel with vinyl insulation and a Mylar-lined sleeve. Copper gives you the conductivity for power and control runs; the Mylar liner backs up the vinyl so the insulation does not split at the crimp when the tool compresses the sleeve.
6) Do I need a special crimper for Sta-Kon insulated terminals?
Use an insulated-terminal crimper with the blue (16-14 AWG) nest. Insulation-supported terminals like the RB2237M are crimped through the sleeve in a single cycle, so a bare-terminal or open-barrel die will cut the vinyl instead of forming the barrel. Match the die color to the terminal color and you get the right compression.
7) Is the Sta-Kon RB2237M made in the USA?
Yes, country of origin is the United States, which matters if you are filling a government, school district, or federally funded job with domestic-sourcing language in the specification.
8) What is the exact part number to order this terminal by?
Order it as Sta-Kon RB2237M. That is the manufacturer part number for the blue vinyl insulated locking fork terminal, 18-14 AWG, No. 8 stud.
