3M 7000133327 Block Fork Vinyl Insulated Terminal

Product Description

The 3M 7000133327 is a vinyl insulated block fork terminal designed for secure, vibration-resistant wire terminations in electrical panel and control wiring applications. Also referenced as MV14-10FBX, this terminal features a forked tongue profile that slides under a screw or stud without removing the fastener completely, making it a practical choice for terminal blocks and bus bar connections. The vinyl insulation sleeve provides basic protection against incidental contact and helps maintain wire organization in tight wiring compartments. Sold in bottles of 100, this terminal is well suited for service stock and panel shop use.

Block fork terminals of this style are commonly installed in residential and light commercial electrical panels, motor control centers, and low-voltage control wiring scenarios. Electricians and panel builders use these terminals when connecting branch wiring to terminal strips or bus bars where screw access is limited or where a tool-free disconnect is advantageous. The forked design is especially useful in retrofit and service situations where the circuit must remain partially assembled during the connection process.

Key Features

• Forked tongue profile allows installation without fully removing the terminal screw
• Vinyl insulation sleeve provides protection against incidental contact at the termination point
• Sold in bottles of 100 for efficient service stock management
• Compact form factor suited for terminal block and bus bar applications
• Also known by the internal reference MV14-10FBX for cross-referencing purposes

Compatibility

Designed as an OEM-style vinyl insulated fork terminal suitable for use with standard terminal blocks, bus bars, and screw-type termination points common in residential and light commercial electrical wiring applications.

Installation Notes

Installation is typically performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before making any terminal connections. Use the correct crimping tool rated for the wire gauge being terminated to ensure a reliable mechanical and electrical connection. Do not rely on the vinyl insulation sleeve as the primary insulation method for live conductors.
