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.; 4″ = 4.00″ 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 (fits 1-7/8″ actual on many 2″ frames).
• Plan Hinge Count: Most single leaves use two hinges; tall/heavy gates may use 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.
