3M 7000133379 Locking Fork Terminal Yellow 10 Stud Crimp 25pk

Product Description

The 3M 7000133379 is a locking fork terminal designed for secure, vibration-resistant electrical connections in panel wiring, control enclosures, and field termination work. The partially insulated, yellow-coded body identifies it as a terminal rated for the applicable wire gauge range. It features a crimp connection type and heat shrink insulation for a reliable mechanical and electrical bond. The fork width measures 0.32 inches and the overall length is 1.0 inch, making it suited for tight terminal block and stud installations. This terminal meets CSA and UL listing requirements, confirming compliance with widely accepted North American electrical safety standards. Licensed electricians and control panel technicians are the primary installers.

This locking fork terminal is used in residential and commercial electrical applications where a No. 10 stud size is required. Typical install scenarios include motor control panels, HVAC equipment wiring compartments, and electrical distribution enclosures where terminals must remain secure under vibration or mechanical stress. The locking fork design resists accidental disengagement from the stud, offering an advantage over standard open-barrel fork terminals in high-vibration environments. Each package contains 25 terminals, and the minimum order quantity is 1 package.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or removing any wiring. Use a calibrated ratchet crimping tool appropriate for the terminal gauge to ensure a full, reliable crimp — never use pliers or uncalibrated tools as substitutes. Verify stud torque requirements per the equipment manufacturer's terminal block specifications before securing the fork.
