3M 7000133646 Block Fork Terminal 12-10 Awg Stud 10

Product Description

The 3M 7000133646 is a vinyl insulated block fork terminal designed for use in terminal block applications where a standard fork terminal will not lie flat against the barrier. Accepts wire ranging from 12 to 10 AWG and fits a number 10 stud size. The flat-sided profile keeps the terminal flush against the barrier portion of the terminal block, maintaining a clean and secure connection in multi-circuit panel and control wiring installations. Electricians and control panel builders use this terminal where space between barrier sections is limited and a conventional fork would interfere with adjacent connections.

This terminal is suited for residential and light commercial electrical applications, particularly in control panels, junction boxes, and multi-pole terminal block assemblies. The vinyl insulation provides a protective sleeve over the barrel, which helps guard against incidental contact and conductor movement after termination. Sold in packs of 10, the terminal is appropriate for jobs requiring a moderate quantity of consistent, insulated block fork connections.

Key Features

• Flat-sided block fork profile designed to lie flush against terminal block barriers
• Accepts 12-10 AWG wire range for flexible conductor sizing
• Fits number 10 stud size
• Vinyl insulation sleeve for conductor protection at the barrel
• Same mechanical strength as standard fork terminals
• Sold in packs of 10 for small-quantity job needs

Compatibility

Designed as an OEM-style replacement and new-installation terminal for use in barrier-style terminal block assemblies accepting number 10 stud hardware and 12-10 AWG conductors.

Installation Notes

Installation is typically performed by a licensed electrician or qualified control panel technician. De-energize and lock out the circuit before terminating or removing any wiring. Use a calibrated ratcheting crimping tool sized for insulated fork terminals to ensure a secure crimp that does not damage the vinyl sleeve. Follow NEC guidelines for conductor sizing, termination torque requirements listed on the terminal block, and panel wiring practices.
