3M 7000133323 Block Fork Vinyl Insulated Terminal

Product Description

The 3M 7000133323 is a vinyl-insulated block fork terminal designed for secure, reliable electrical connections in wire termination applications. This connector accepts a threaded stud or screw and provides a stable, low-resistance contact point at the end of a conductor. The vinyl insulation sleeve protects the crimped barrel from abrasion and incidental contact, reducing the risk of shorts in panel and junction box wiring. Licensed electricians and instrumentation technicians install these terminals during control panel builds, motor wiring, and equipment service work.

Block fork terminals of this type are used in residential and light commercial electrical panels, motor control centers, and industrial control enclosures where a secure screw-down termination is required. The open-fork profile allows the terminal to remain in place on the stud while the fastener is loosened, which simplifies maintenance and reconnection work. These terminals are sold in bottles of 100, making them practical for bench stock in electrical shops and service vans.

Key Features

• Vinyl insulation provides electrical protection and abrasion resistance at the barrel
• Block fork profile allows connection without fully removing the mounting fastener
• Crimp-style installation for fast, consistent termination
• Sold in bottles of 100 for convenient shop and field stocking
• Compact form factor suits panel wiring and tight enclosure layouts

Compatibility

Designed as an OEM-style vinyl-insulated block fork terminal for use in standard electrical termination applications requiring a screw or stud connection point.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines. De-energize and lock out the circuit before terminating or removing any conductors. Use a calibrated crimping tool rated for vinyl-insulated terminals to ensure a proper mechanical and electrical crimp. Do not solder over a crimped terminal, as this can introduce brittleness at the barrel transition.
