EFA050 Pre-Galvanized Steel Plate Electric Fence Wire Strainer Spring Clip Aluminum Spool 4mm In-Line Tensioner

The EFA050 in-line wire strainer is a precision tensioning tool for electric fence installations, designed to maintain optimal wire tension without the need for knot tying. Constructed with a pre-galvanized ribbed steel frame and a tapered die-cast aluminum spool, this strainer accommodates up to 4mm gauge wire and features a spring-loaded locking clip for secure, tool-free tension adjustment. The two-hole design allows wire to run freely through the body, simplifying both initial setup and periodic re-tensioning.

• Pre-galvanized steel plate frame with ribbed construction delivers rust resistance and structural rigidity for outdoor fence line duty
• Tapered die-cast aluminum spool with 2 extra teeth provides easier wire tightening action, requiring fewer clip turns to hook into the next tooth position
• Increased spool hub thickness supports heavy gauge wire up to 4mm (.15748") for high-tensile, barbed, and woven wire applications
• High-quality spring-loaded stainless steel locking clip maintains secure tension even under fluctuating load and temperature conditions
• Two-hole through-body design enables wire threading without tying additional knots, reducing installation time and improving reliability
• In-line configuration integrates seamlessly into existing fence runs without disconnecting end posts or removing insulators
• Compact form factor suitable for both permanent fencing and temporary grazing rotation systems

Essential for maintaining consistent wire tension across electric fence installations on livestock farms, ranches, and equestrian properties. The EFA050 is compatible with high-tensile steel wire, barbed wire, and woven wire fencing systems up to 4mm gauge. Its in-line design allows for mid-span tensioning without dismantling existing fence sections, making it ideal for both new construction and fence maintenance programs.
