The GBC 18.3922.50 is a pre-insulated eyelet terminal for cables in the 4–6 mm² range (AWG 12–10). The Φ8.4mm hole accepts M8 screws with shank diameters from 5.5mm to 8mm, and the PVC sleeve over the tin-plated copper barrel is rated to 300V.

At 34mm long with a 15mm external diameter, this is among the larger terminals in the GBC pre-insulated range, suited to earthing rails, motor feed connections, and heavy-duty distribution panels. The yellow sleeve identifies the 4–6 mm² conductor range. Each pack contains 10 pieces.
