Sample Pack: Try 3 Wire Joiner Sizes

Not sure which size you need? The Spiralfast sample pack contains 3 each of the SF20, SF25 and SF30 wire joiners (9 total), so you can try them on your own wire before buying a full pack.

• SF20 for 1.8mm–2.0mm wire (approx. 14–15 gauge): dripper lines, tomato trellis and other small gauge wire

• SF25 for 2.5mm–2.8mm wire (approx. 11.5–12.5 gauge): fencing and trellis high tensile wire

• SF30 for 2.8mm–3.15mm wire (approx. 10–11.5 gauge): fencing and trellis high tensile wire

Every Spiralfast wire joiner is reusable and applied by hand, with no crimping tools or ratchets needed. Happy with your size? Full packs of 20, 50 or 1000 are available in our shop.
