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: 1-3/4" 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: 50 Lb contractor box - bulk pack for full-perimeter agricultural fence runs and multi-fence installs
• 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: Same 1-3/4" leg length in the contractor bulk pack - choose this size when staking out full-perimeter pasture fence, running multiple acres of high-tensile or woven wire field fence, or staffing a fence crew. A 50 Lb box holds roughly 3,400-3,800 staples (varies by exact dimensional weight) - enough for several hundred line posts.
