FSNY / FSNYD Nylon Convex Fork Terminals
FSNY and FSNYD nylon convex fork terminals are copper fork terminals with insulated sleeves. FSNY is the single-crimp style; FSNYD adds a copper tube sleeve for double crimp.
- One combined listing with 29 paired rows and 58 model codes.
- Red, blue and yellow groups cover 0.5–1.5, 1.5–2.5 and 4–6 mm² conductors.
- Select by conductor group, bolt size and B, F, L, A, E, D1 and D2 dimensions.
Overview
FSNY / FSNYD Nylon Convex Fork Terminals are insulated copper convex fork terminals for bolted electrical connections. The FSNY models use a single crimp; their matching FSNYD models use a double crimp with a copper tube sleeve. Both styles are combined below for direct model and dimension comparison.
Features
- Paired crimp styles: each listed FSNY model has an FSNYD double-crimp counterpart.
- Fork connection: the open fork fits the corresponding bolt size shown for each model.
- Copper terminal and insulated sleeve: the source catalog identifies copper terminal material and a nylon sleeve.
- Color-coded size groups: red, blue and yellow identify the three listed conductor ranges.

Selection Guide
Select the conductor range first, then match the d2 fork opening to the intended bolt. Compare B, F, L and the group dimensions A, E, D1 and D2 with the available installation space, and specify FSNY or FSNYD by crimp style.
