Join and Tension Standard Agricultural Wire in One Step — Gripple Medium Wire JoinerThe Gripple Medium Wire Joiner joins and tensions wire in a single device — no knots, no crimps, no separate tensioning hardware. Inside every Gripple are high-precision gear-toothed ceramic rollers that grip each wire and allow it to move in one direction only. The moment load is applied, the rollers bite into the wire and lock it in place — the harder the pull, the tighter the grip.The Medium Gripple is sized for standard agricultural wire gauges including 12.5 gauge hi-tensile and 12.5 gauge barbed wire. Adjustable and re-tensionable year after year as wire stretches and settles — no cutting and re-joining required.FeaturesJoin & Tension in OneJoins two wire ends and tensions the connection in a single device — no separate tensioning hardware needed.Gear-Toothed Ceramic RollersHigh-precision ceramic rollers grip the wire under load — the harder the pull, the tighter the lock. Ceramic construction provides optimum corrosion resistance.Faster Than Tying & KnottingInstalls in seconds compared to hand-tying — saves significant time and labor on large fence builds.Adjustable & Re-TensionableCan be re-tensioned year after year as wire stretches and settles — no need to cut and re-join.High Load HoldingEngineered for the tension demands of permanent agricultural fence systems.Compatible with Standard Agricultural WireWorks with 12.5 gauge hi-tensile and 12.5 gauge barbed wire.Specifications Size: Medium Compatible Wire: 12.5 gauge hi-tensile, 12.5 gauge barbed wire, and standard agricultural wire gauges Roller Material: High-grade ceramic Tensioning Tool: Gripple Torq Tool (sold separately) Application: Agricultural fence wire joining and tensioning Faster, stronger, re-tensionable — the Gripple Medium Wire Joiner joins and tensions standard agricultural wire in one step without tying a single knot.
