Panduit EV10-6LFB-Q StrongHold Vinyl-Insulated Locking Fork Terminal
Overview
The Panduit EV10-6LFB-Q is a vinyl-insulated locking fork terminal from the StrongHold™ series, designed for 12–10 AWG wire terminations at #6 screw sizes. At 1.04 inches overall length and 0.34 inches wide, this tinned (zinc-plated) crimp terminal delivers a mechanically secure, vibration-resistant connection in panel wiring, control cabinet builds, and security system power distribution runs where a standard fork terminal would back out under service conditions. It ships in a 25-count package (carton quantity 250), making it practical for both small-run installs and volume panel work.
The locking fork design — the differentiator over standard open-barrel fork terminals — uses a captive geometry that prevents the terminal from lifting off the screw under vibration or repeated service cycles. If you've had a fork terminal work loose on a security panel or access control power supply after a few years of heat cycling, this is the spec that addresses it.
Key Features
- Locking Fork Design: The captive locking geometry keeps the terminal seated on the screw stud even under vibration and thermal cycling — a meaningful difference in control cabinets, security enclosures, and anywhere wire terminations are not revisited after commissioning.
- 12–10 AWG Wire Range: Covers the most common security and low-voltage power wire gauges — 12 AWG for longer home-run runs and 10 AWG for higher-current feeds — without needing two different terminal SKUs on the same job.
- #6 Screw Size: Matched to the terminal block and panel screw sizes typical in security system power supplies, access control boards, and structured wiring enclosures. Verify your terminal block accepts #6 hardware before ordering.
- Zinc-Plated (Tinned) Finish: The galvanized finish resists oxidation at the contact interface, preserving low-resistance connections over the product lifespan — relevant in humid environments like mechanical rooms or outdoor-rated enclosures with condensation risk.
- Vinyl Insulation, UL587-H Flammability Rating: UL587-H-rated insulation meets the flammability requirements for use in listed electrical assemblies. In a panel that needs to carry a UL listing, using UL-listed components throughout — including terminals — is part of maintaining that listing.
- UL Listed and CSA Certified: UL listing (E52164) and CSA certification (LR31220) mean the EV10-6LFB-Q is independently verified for the electrical and mechanical requirements of its rating class. Required documentation for AHJ submittals on listed panel builds.
- Compact Form Factor (1.04" × 0.34"): The 1.04-inch overall length and 8.6 mm (0.34 in) width keep the terminal footprint tight in dense terminal blocks — useful in shallow enclosures or multi-row terminal strips where larger crimp terminals cause clearance issues.
- Compatible with Panduit Crimp Tools: Designed for use with Panduit CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, and CT-2500 (CT-2550CH) crimping tools. Using the correct matched tool is required to achieve the specified crimp geometry — an incorrect tool can produce a mechanically weak or electrically marginal crimp that passes visual inspection but fails under load.
Integration & Compatibility
The EV10-6LFB-Q (often searched as EV10 6LFB Q) is a wire-termination component that installs at the end of a 12–10 AWG conductor and connects to any standard #6 screw terminal point. It is compatible with Panduit's CT-series crimp tools listed above. Cross-reference competitor part numbers LFV10-6, TP10-6LF, and TV10-6LF-XV when sourcing on existing BOMs — the EV10-6LFB-Q is the Panduit equivalent. The locking geometry requires the mating screw to be properly torqued to retain the locking benefit; a loose screw negates the captive design.
For larger wire gauge requirements or higher-current terminations in the same panel build, review the broader Panduit wire termination catalog for compatible fork terminal variants. If you are wiring PoE switches or security NVR enclosures and need to plan the full power distribution run, see the wire termination category for complementary ferrules, ring terminals, and splice connectors. For structured cabling accessories that pair with Panduit termination hardware, the cable management category covers cable ties, conduit fittings, and raceway systems from the same manufacturer.

Frequently Asked Questions
Q: What wire gauge range does the EV10-6LFB-Q accept?
A: The EV10-6LFB-Q is rated for 12–10 AWG conductors. It is not suitable for finer gauges (14 AWG and smaller) or heavier wire (8 AWG and larger).
Q: What screw size does this terminal fit?
A: The EV10-6LFB-Q is designed for #6 screw hardware. Verify your terminal block or panel stud uses #6 screws before ordering — it will not seat correctly on #8 or #10 hardware.
Q: Which Panduit crimp tools are compatible with this terminal?
A: Panduit specifies the CT-100A, CT-600-A (CT-550CH), CT-1550, CT-1551, and CT-2500 (CT-2550CH) for the EV10-6LFB-Q. Using a non-specified tool risks a substandard crimp that may not provide full mechanical or electrical performance.
Q: Is the EV10-6LFB-Q UL listed?
A: Yes. It carries UL listing 587H under file E52164 and CSA certification under LR31220. The vinyl insulation meets UL587-H flammability requirements, supporting use in UL-listed panel assemblies.
Q: How many terminals come in a package?
A: Standard package quantity is 25 terminals. Full carton quantity is 250 (10 packages per carton).
Q: What is the difference between this and a standard (non-locking) fork terminal?
A: A standard open-barrel fork terminal can lift off a screw under vibration or during service — a locking fork uses a captive geometry that keeps the terminal seated on the stud. The EV10-6LFB-Q locking design is the appropriate choice for applications where terminals are not routinely re-inspected, such as sealed enclosures or control cabinets subject to vibration.
The EV10-6LFB-Q gets specified on jobs where a standard fork terminal technically works but has a failure mode you don't want to revisit three years post-commissioning. The locking geometry — combined with the zinc-plated finish and UL587-H vinyl insulation — makes this a terminal you install once and trust. At 1.04 inches long and 0.34 inches wide, it stays compact enough for dense terminal blocks in shallow security enclosures without requiring special clearance planning.
Technical Highlights:
- 12–10 AWG coverage: Spans the two most common security panel power wire gauges in a single SKU — saves carrying two terminal part numbers on a mixed-gauge job.
- UL listed (E52164) / CSA certified (LR31220): Both marks are verifiable by file number, which matters when the panel build needs AHJ documentation or a third-party inspector is reviewing component compliance.
- Tool compatibility (CT-100A through CT-2500 series): Panduit publishes the compatible crimp tool list for this terminal — using a matched tool is the only way to get the specified mechanical and electrical crimp performance. An off-brand or unverified tool on these terminals is a quality escape waiting to happen.
Deployment Considerations:
- Confirm screw size at the termination point before ordering — the EV10-6LFB-Q is sized for #6 hardware specifically, and a #8 or #10 stud won't engage the locking feature correctly.
- The locking benefit is only realized with proper torque on the mating screw; in vibration-prone enclosures, include screw torque in your commissioning checklist rather than assuming hand-tight is sufficient.
Best fit for security panel builds, access control power distribution, and structured wiring enclosures where 12–10 AWG feeds terminate at #6 screw blocks and the installation won't be routinely reopened for re-inspection.
