Panduit EV18-10LFB-L StrongHold Insulated Vinyl Locking Fork Terminal

Overview

The Panduit EV18-10LFB-L is a vinyl-insulated locking fork terminal from the StrongHold™ line, rated for 22–18 AWG wire and designed for #10 screw connections. At 0.97 inches overall length and 0.33 inches (8.4 mm) width, it is a compact, production-grade terminal built for wire-termination applications where vibration resistance and UL listing matter. Sold in packages of 50 with a carton quantity of 500, the EV18-10LFB-L suits both small-run panel builds and high-volume assembly environments.

Key Features

• Locking Fork Design: The locking tab keeps the terminal seated on the screw even before full torque is applied — reduces drop-back and misalignment during assembly, which matters on dense terminal strips where re-seating costs time.
• 22–18 AWG Wire Range: Covers the most common control-circuit and signal-wire gauges in security panels, access control wiring, and low-voltage instrument loops — one terminal SKU handles the majority of field connections in these applications.
• Vinyl Insulation, UL 587H Rated: UL 587H flammability classification means the insulation meets the standard for insulated terminals — not just a generic sleeve. This matters when specifying for panels with a UL listing requirement on components.
• Tin (Verzinkt) Finish: Electroplated zinc (tin) over the copper barrel provides corrosion resistance in indoor enclosure environments and ensures reliable conductivity at the crimp joint over time.
• UL Listed and CSA Certified: Carries UL listing 587H E52164 and CSA certification LR31212 — both marks are relevant for NEC-compliant panel builds and Canadian installations. Dual-listed components simplify cross-border project documentation.
• Compatible Crimping Tools: Verified for use with Panduit CT-100A, CT-600-A (CT-500CH and CT-550CH), CT-1550, and CT-1551 crimp tools — not a universal crimp; using the correct tool die is required to achieve the specified mechanical connection.
• Pack Quantity Options: Package quantity of 50 suits smaller jobs or stocking variety; carton quantity of 500 is the right pull for volume termination work on larger panel builds or distribution projects.

Integration & Compatibility

The EV18-10LFB-L (often searched as EV18 10LFB L) is engineered for use with Panduit's CT-series crimp tools. Cross-reference competitor part numbers 83-7031, TP16-10LF, and TV18-10LF-XV for direct substitution verification — confirm wire gauge and screw size match before substituting. This terminal is categorized under wire-termination and is appropriate for control panels, security system enclosures, access control hardware installations, and any low-voltage wiring application requiring a listed fork terminal on a #10 screw lug point.

Frequently Asked Questions

Q: What wire gauge range does the EV18-10LFB-L accept?

A: The EV18-10LFB-L is rated for 22–18 AWG wire, covering the most common control and signal wire sizes used in security and low-voltage panel wiring.

Q: What screw size is this fork terminal designed for?

A: It is designed for #10 screw connections, which is a standard size in terminal blocks and equipment lugs used in commercial panel builds.

Q: Is the EV18-10LFB-L UL listed?

A: Yes. It carries UL listing 587H file number E52164 and CSA certification LR31212, making it suitable for NEC-compliant and Canadian installations requiring listed terminal components.

Q: Which crimp tools are compatible with this terminal?

A: Panduit specifies the CT-100A, CT-600-A (CT-500CH), CT-600-A (CT-550CH), CT-1550, and CT-1551 crimp tools for use with the EV18-10LFB-L. Using a non-specified tool may not achieve the required mechanical crimp.

Q: What is the package and carton quantity?

A: The EV18-10LFB-L ships in packages of 50. Full carton quantity is 500 pieces, suited for volume termination projects.

Q: Are there direct cross-reference substitutes for this terminal?

A: Panduit lists competitor part numbers 83-7031, TP16-10LF, and TV18-10LF-XV as cross-references. Verify wire gauge, screw size, and insulation rating before substituting any terminal.

Karl Wilson

The EV18-10LFB-L is one of those terminals that earns its place on the BOM by being exactly what it claims: a UL 587H listed, CSA-certified locking fork rated for 22–18 AWG on a #10 screw, with a tin-plated barrel and vinyl insulation that meets flammability requirements — not just a generic crimp terminal dressed up with a brand name.

Technical Highlights:

• Locking Tab Geometry: The fork's locking feature holds the terminal on the screw during positioning — on a 20-point terminal strip, that difference between drop-back and stay-in-place directly impacts termination throughput on a busy panel build.
• Dual Listing (UL E52164 / CSA LR31212): Both marks are on the same part, so you are not sourcing two different terminals for US and Canadian panels on a cross-border security integration project.
• Tin Finish over Copper Barrel: Electroplated tin resists oxidation inside enclosed panels, maintaining low-resistance contact at the crimp joint over the service life of the installation — relevant in humid or temperature-cycling mechanical rooms.

Deployment Considerations:

• Crimp tool compatibility is specific: the CT-100A, CT-600-A (CT-500CH / CT-550CH), CT-1550, and CT-1551 are the verified tools. A mismatched die will not produce a listed crimp — confirm before pulling from a different tool kit on the job site.
• Overall length is 0.97 inches — verify clearance in high-density terminal blocks before spec'ing; the locking tab adds a small retention profile that may require slightly more screw travel than an open-barrel fork.

This terminal is well-suited for commercial security panel builds and access control enclosure wiring where a dual-listed, vibration-resistant fork terminal on 18–22 AWG control runs is a spec or inspection requirement — not a general-purpose jobsite crimp.
