Thomas Betts RA18-6FL Locking Fork Terminal 6 Stud

Product Description

The THOMAS BETTS RA18-6FL is a partially insulated locking fork terminal designed for secure, vibration-resistant wire terminations in electrical panels, control wiring, and equipment connections. The locking fork design prevents accidental disengagement from stud terminals, making it a reliable choice where mechanical security matters. Rated at 600 volts, the RA18-6FL features a copper contact body with a TiN (titanium nitride) plating and a red nylon insulation sleeve. The crimp connection method provides a gas-tight, mechanically sound termination when applied with the correct tooling. Red color coding indicates compatibility with 18 AWG wire ranges standard to the color convention used across this terminal series.

The RA18-6FL is suited for residential and commercial electrical work, HVAC low-voltage control wiring, panel terminations, and industrial equipment connections where a number 6 stud size is used. The locking fork style is commonly specified in applications subject to vibration, repeated servicing, or where terminal walk-off is a documented concern. This terminal is sold in packages of 100 units, making it practical for service vans, panel shops, and production environments.

Key Features

• Locking fork design prevents terminal from disengaging under vibration or movement
• 600 volt rating suitable for a wide range of electrical and control wiring applications
• TiN-plated copper contact for corrosion resistance and reliable conductivity
• Red nylon partial insulation sleeve for color-coded wire range identification
• Crimp termination provides a gas-tight mechanical connection
• Meets UL 486A, UL 486B, CSA 22.2, RoHS, and UL 94 V-2 flammability standards

Compatibility

Designed for use with number 6 stud sizes. Intended as a standard crimp locking fork terminal for residential, commercial, and light industrial electrical termination applications where a partially insulated, red-coded terminal is specified.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or removing any wiring. Use a calibrated crimp tool rated for the wire gauge and terminal series to ensure a proper gas-tight crimp. Do not solder over a crimp termination, as this can compromise the mechanical and electrical integrity of the connection.
