The GBC fork-shaped pre-insulated terminal F.4 (model 18.3932.20) terminates heavy-gauge flexible cables at M4 screw connections. The factory-fitted yellow PVC sleeve insulates the crimp zone and identifies the cable size range at a glance.

Each terminal accepts cable cross-sections from 4 to 6mm² (AWG 12–10) and is rated to 300V. The compact 21.2mm length and 6.4mm external diameter fit neatly into panel terminal blocks and distribution boards. The pack contains 10 terminals.

Key Features

• Fork (spade) shape for M4 screw connections — no need to remove the screw fully
• Pre-fitted yellow PVC insulation sleeve for a ready-to-crimp finish
• Tin-plated copper contact for corrosion resistance
• Screw hole diameter 4.3mm suits standard M4 hardware
• Body dimensions: 21.2mm length, 6.4mm external diameter

Product Benefits

• Pre-insulated design speeds up panel wiring without additional sleeving steps
• Yellow colour coding identifies the 4–6mm² cable range for fast visual verification
• 300V maximum voltage rating covers most low-voltage control and power circuits
• Tin-plated contact resists oxidation over time for stable conductivity
• Fork shape allows connection and disconnection with the screw left partially in place
