The GBC fork-shaped pre-insulated terminal (MPN 18.3930.20) is an open-barrel spade connector designed for secure, tool-free disconnection on M3.5 screw terminals. The PVC-insulated red barrel fits cable cross-sections of 0.5–1.5 mm² (AWG 22–16) and the tin-plated copper contact ensures reliable conductivity.

The 3.7mm screw hole fits M3.5 fasteners found in control panels, junction boxes, and small appliance wiring. With a total length of 21.2mm and an external diameter of 5.7mm, it is among the most compact fork terminals in the GBC range. Supplied in packs of 10, colour-coded red for the 0.5–1.5 mm² wire range.

Key Features

• Fork (spade) shape allows terminal to be connected or disconnected without removing the screw fully
• Pre-insulated red PVC barrel eliminates the need for separate sleeving after crimping
• Tin-plated copper contact for reliable conductivity and corrosion resistance
• M3.5 screw hole (Φ3.7mm) for use on small-screw terminal blocks and control panels
• Rated to 300V maximum voltage

Product Benefits

• Open fork design allows the wire to be added or removed without undoing the terminal screw completely
• Pre-insulated barrel provides electrical insulation immediately after crimping — no extra steps
• Red colour coding for 0.5–1.5 mm² makes cable identification quick during installation and maintenance
• Compact 21.2mm length keeps wiring neat inside enclosures with limited space
• Pack of 10 suits panel wiring, control cabinet connections, and appliance repairs
