One Piece 45 Degree Single Barb Arm (Pressed Steel)

Pressed steel one-piece barb wire arms at 45 degrees—both single and double types—are essential components in chain link fencing systems designed for enhanced security. These are also called Extension arms. Here's how each type is used:

• Creates an angled deterrent against climbing, extending barbed wire at a 45° outward angle from fence posts.
• Enhances security on straight fence runs when installed on line posts.
• Strengthens corners or ends when used on terminal or corner posts (double-arm variant).
• Secured with set screws or brace band—no welding required.
• Often galvanized or powder-coated, these arms resist rust and environmental wear, ideal for outdoor use.
