3M 7000133394 Locking Fork Terminal Red 6 Stud Crimp

Product Description

The 3M 7000133394 is a red, partially insulated locking fork terminal designed for secure, vibration-resistant electrical connections in panel wiring, control systems, and equipment termination applications. It uses a crimp connection method and features a 1/4-inch fork width sized for a number-6 stud. The terminal measures 1 inch in overall length and 0.03 inches thick. Partial insulation keeps the barrel protected while leaving the fork exposed for positive contact at the stud. Licensed electricians and control panel assemblers install this type of terminal during new construction, retrofit, and MRO work where reliable low-voltage wiring terminations are required.

This locking fork terminal is suited for residential and commercial electrical wiring, HVAC control panel assembly, and light industrial equipment connections where a number-6 stud termination point is present. The red color coding follows standard AWG wire-range identification, helping technicians sort and verify terminations during installation and inspection. The crimp-style design allows for fast, consistent installation using standard crimping tools without requiring soldering. Packages contain 25 terminals, making this SKU appropriate for bench stock and service kit replenishment.

Key Features

• Locking fork design resists pullout and maintains contact under vibration
• Partial insulation protects the crimp barrel while leaving the fork accessible at the stud
• Number-6 stud size with 1/4-inch fork width for precise fitment
• Crimp termination for fast, solder-free installation with standard tools
• CSA Certified and UL Listed — meets CSA LR22190 and UL File E23438
• Red color coding for quick wire-range identification during assembly and inspection

Compatibility

Designed for use with number-6 studs in residential and commercial electrical panels, HVAC control wiring, and light industrial equipment termination points where a 1/4-inch fork-width crimp terminal is specified.

Installation Notes

Installation is performed by licensed electricians or qualified control panel technicians. De-energize all circuits and verify absence of voltage before terminating or removing wiring. Use a calibrated crimping tool rated for the wire gauge and terminal size to ensure a gas-tight crimp connection. Work in accordance with applicable NEC requirements and any equipment manufacturer wiring guidelines.
