This pressed steel arm hinge is a contractor-grade solution for commercial chain link swing gates and double-drive gates. The galvanized finish resists weathering, while the arm design works with a post-mounted hinge to allow a full 180° swing—maximizing clear opening for vehicles and equipment. Adjustable U-bolts on the gate side simplify installation and fine-tuning on 1-5/8″ or 2″ uprights. Use two hinges for most single gates; large or heavy leaves may require three.

Buying Guide

• Match Post Size: Choose the arm hinge size that matches your post O.D. (e.g., 2-1/2″ → 2-3/8″ O.D.; 3″ → 2-7/8″ O.D.; 3-1/2″ → 3-1/2″ O.D.; 4″ → 4.00″ O.D.; 4-1/2″ → 4.50″ O.D.; 6-5/8″ → 6.625″ O.D.).
• Check Frame O.D.: Gate-side U-bolts clamp to 1-5/8″ or 2″ uprights (many 2″ frames are 1-7/8″ actual).
• Plan Hinge Count: Most single leaves use two hinges; tall/heavy gates may require three. Double drives use two hinges per leaf.
• Verify 180° Clearance: Ensure the gate can rotate alongside the fence line without striking obstacles when fully opened.

Comparison to Other Solutions

• Pressed Steel vs. Malleable Steel Arm Hinges: Both styles are galvanized and designed for heavy use; selection often comes down to project preferences and matching existing hardware.
• Arm Hinge vs. 180° Adapters: Hinge Adapters can retrofit 90° hinge setups to 180°; arm hinges provide 180° swing out of the box with fewer parts.
• Arm Hinge vs. Bulldog/Butt/Box Hinges: Bulldog/butt/box hinges typically swing ~90°; arm hinges are intended for full 180° operation.
