3M 7000133369 Locking Fork Terminal Vinyl Insulated

Product Description

The 3M 7000133369 is a vinyl-insulated locking fork terminal sold in bottles of 100, referenced under the series designation MV14-6FLX. Locking fork terminals provide a secure, vibration-resistant connection to binding posts and terminal blocks without requiring full removal of the fastener. The forked tongue locks under the screw head to prevent accidental pull-out during service. These terminals are suited for low-voltage control wiring, panel work, and field terminations where a dependable mechanical connection is required. Electricians and HVAC controls technicians install these during panel builds, control board wiring, and equipment retrofits.

Locking fork terminals in this style are commonly used in residential and light commercial electrical and HVAC applications. Typical installations include terminal block wiring in air handlers, furnace control panels, condensing unit disconnects, and general low-voltage control circuits. The vinyl insulation provides electrical isolation at the termination point and protects the conductor end from abrasion. The 100-count bottle format suits both service trucks and shop bench use where volume terminations are performed regularly.

Key Features

• Locking fork design resists pull-out and vibration loosening at screw terminals
• Vinyl insulation provides electrical isolation and conductor protection
• 100-count bottle format for stock and service vehicle use
• Series designation MV14-6FLX for cross-reference ordering
• Lightweight construction at 0.01 pounds per unit

Compatibility

Designed as an OEM-style replacement and general-use locking fork terminal compatible with standard screw-type terminal blocks and binding posts used in low-voltage electrical and HVAC control wiring applications.

Installation Notes

Locking fork terminals are installed by licensed electricians and HVAC technicians following applicable NEC requirements. De-energize the circuit completely before terminating or re-terminating conductors. Use a properly calibrated crimping tool rated for the conductor gauge being terminated to ensure a secure mechanical and electrical connection. Do not over-tighten the binding screw, as this can deform the terminal fork and reduce holding strength.
