Heavy-duty #9 gauge fence staple with a lock-barb design - small double-cut barbs notched into each leg that grip the wood grain on drive and resist back-out under wire tension. Use these for attaching barbed wire, woven wire field fencing, chain-link tension wire, and poultry/aviary mesh to wood line posts and corner posts. Hand-drive with a fence staple hammer or claw hammer (not for pneumatic staplers, which use a different collated staple style).

• Size: 1-1/4" leg length
• Gauge: #9 (~0.148" wire diameter) for grip and pull-out resistance under steady wire tension
• Barb design: Double-cut lock barbs on each leg - the barbs flare open on drive and bite into wood grain on any back-out attempt
• Material: Carbon steel
• Finish: Galvanized - resists rust on exposed fence-post applications
• Packaging: 8 Lb resealable pail - residential and small-property work, roughly one side of a standard back-yard run
• Applications: Barbed wire, woven wire field fencing, high-tensile fence, chain-link tension wire, poultry netting, aviary mesh, electric fence wire (insulated)
• Drive method: Hand drive only - use a fence staple hammer or claw hammer; not collated for pneumatic guns
• Install: Drive at a slight angle across the wood grain so the two legs splay apart on either side of the wire; leave a small gap (1/16-1/8") between the staple crown and the wire to allow for thermal expansion and wire flex - tight-driven staples cut into the wire and split the post

Tip: Shortest leg in the line - use for lighter wire gauges (16 ga chicken wire, hardware cloth, aviary mesh, and thin electric fence wire) on softwood posts like cedar or pine where deeper leg insertion would risk splitting. Drive perpendicular to the grain on small-diameter posts so the barbs catch grain on both legs.
