The Spiralfast SF40 wire joiner is built for 4mm wire (approximately 8 gauge), making it a strong high tensile wire joiner suited to fencing and other large gauge wire applications. As a reusable wire joiner, it's applied and tensioned entirely by hand — no crimping tools, ratchets, or special equipment needed. Available in packs of 20 or 50.
A faster, stronger alternative to wire knots
Traditional wire knots take practice to tie and can weaken the wire at the bend, especially on heavier gauge wire like this. The SF40 wire joiner skips the knot-tying entirely — just apply it by hand, and re-tension anytime by simply reapplying it.
