Panduit EV18-6LFB-Q StrongHold Vinyl-Insulated Fork Terminal

The Panduit EV18-6LFB-Q is a StrongHold locking fork terminal engineered for 22-18 AWG stranded copper wire terminations to #6 screw studs. Vinyl insulation provides 600V rated protection while the funnel-entry barrel design guides wire strands during crimp insertion, reducing prep time on high-density terminal blocks and distribution panels. The locking shoulder feature prevents terminal rotation under vibration—critical for industrial access control panels, UPS battery strings, and low-voltage power distribution where connection integrity directly impacts system uptime.

Key Features

• 22-18 AWG wire range with funnel-entry barrel for fast field termination
• #6 screw stud compatibility (0.27" fork width) for standard terminal blocks
• Tin-plated copper construction resists corrosion in HVAC and telecom closet environments
• UL 587H listed and CSA LR31212 certified for NEC/CEC compliant installations
• Locking shoulder design prevents rotation under mechanical stress and vibration
• Vinyl insulation rated for 600V, temperature range -40°C to +105°C
• 0.9" overall length allows clearance in crowded enclosures

The tin-plated copper barrel and fork provide stable contact resistance across temperature cycling, meeting UL 587H flammability requirements for enclosed panels. The 6.9mm fork width matches #6-32 and #6-40 screw terminals commonly found on Altronix power supplies, Securitron lock controllers, and DIN-rail distribution blocks. Crimp tooling compatibility spans Panduit CT-1550/CT-1551 hand tools and the CT-600-A pneumatic crimper with CT-500CH or CT-550CH die sets—the ratcheting hand crimper ensures full-cycle compression even when working overhead in ladder installations. The vinyl insulator extends 0.05" beyond the barrel crimp zone, providing touch-safe protection when terminals are installed at NEC-minimum 0.25" spacing on barrier strips.

Deployment scenarios include 12VDC/24VDC power bus distribution in access control risers, battery interconnects on APC/Eaton UPS systems where wire flexibility is required for service access, and low-voltage relay control wiring in fire alarm panels. The fork configuration allows installation and removal without complete stud disassembly—an advantage over ring terminals when retrofitting existing panels or troubleshooting under time pressure. The locking shoulder engages the terminal block body when the screw is torqued to manufacturer spec (typically 7-9 in-lbs for #6 screws), preventing counter-rotation during adjacent terminations. Bulk packaging in 25-piece bags within 250-piece cartons supports both project kitting and MRO stock replenishment for integrators maintaining consistent crimp tooling and color-coding standards across multi-site deployments.

StrongHold terminals meet the same mechanical pull-out force requirements as Panduit's non-insulated compression lugs but add the installation speed of pre-insulated barrels. This product is UL recognized under file E52164 and CSA certified under LR31212—documentation required for AHJ approval on government and healthcare projects where every component in the low-voltage electrical chain must trace to a listed assembly. The tin-plated finish maintains joint integrity in plenum-rated telecom rooms and coastal installations where humidity accelerates copper oxidation on bare terminals.
