3M 7000133342 Block Fork Terminal Vinyl Insulated

Product Description

The 3M 7000133342 is a vinyl-insulated block fork terminal sold in bottles of 50. Block fork terminals are used to terminate stranded or solid wire conductors at screw-type terminal blocks, allowing a secure, vibration-resistant connection without the wire splaying under the screw head. The vinyl insulation sleeve provides basic electrical isolation at the termination point. These are hand- or tool-crimped connectors installed by electricians and low-voltage technicians during panel wiring, control circuit assembly, and equipment termination tasks. The MV10-8FBX designation indicates the series and wire/stud sizing for this connector style.

Block fork terminals in this style are commonly used in residential and light commercial electrical work, HVAC control panels, motor control centers, and industrial enclosures where screw-terminal blocks are the primary wiring method. They are appropriate for applications where a fork-style lug is preferred over a ring terminal for faster installation and removal from terminal block screws without fully removing the fastener.

Key Features

• Vinyl-insulated sleeve provides electrical isolation at the crimp termination point
• Block fork (spade) lug design allows fast removal from screw terminals without fully loosening the fastener
• Sold in bottles of 50 for bench-stock and service kit replenishment
• MV10-8FBX series designation for consistent sizing and crimp tooling compatibility

Compatibility

Designed as an OEM-style replacement and standard-stock fork terminal for use with screw-type terminal blocks in electrical panels, control enclosures, and HVAC low-voltage wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians. De-energize all circuits before terminating or replacing connectors in a panel or control enclosure. Use a calibrated ratchet crimp tool appropriate for vinyl-insulated fork terminals to ensure a secure mechanical and electrical crimp. Inspect the insulation sleeve after crimping to confirm no cracking or pull-back that would expose bare conductor.
