Engineered for daily service, this galvanized malleable steel butt (box) hinge is a proven choice for commercial and industrial chain link gates. The hinge bolts around the gate post, while the collar wraps the gate upright so the leaf bears on the hinge for a smooth, repeatable swing. Out of the box you get a 90-degree opening in either direction; pair each hinge with a 180-degree adapter to open the gate flat when site logistics demand maximum clearance. Sized for 1-5/8″ or 2″ uprights and available for a wide range of post diameters, this hinge helps you keep installs consistent across sites and gate types.

Buying Guide
- Match the post O.D.: Choose the hinge size for your terminal/post diameter (see specs).
- Select the upright size: The collar accommodates 1-5/8″ or 2″ round gate frames.
- Choose hinge count: Use two hinges on most single gates; add a third for leaves over ~8′ tall or heavier-than-usual builds.
- Plan the swing arc: Standard swing is 90°; add a 180° hinge adapter if you need the leaf to fold back along the fence line.
- Automated gates: These hinges are suitable for operator-driven gates when specified and installed per opener and site requirements.
Frequently Asked Questions
- What’s the standard swing range?
- 90° in either direction. Use a 180° hinge adapter if you need a full fold-back swing.
- Do these work with gate operators?
- Yes. They’re suitable for automated swing gates when properly specified and installed.
- How many hinges do I need?
- Most single leaves use two hinges. Tall or heavy gates (around 8′ and up) typically use three.
- What gate frame sizes will the collar fit?
- 1-5/8″ or 2″ round uprights.
- What gate types are these best for?
- Commercial and industrial chain link: barrier gates, panic-bar gates, large swing leaves, and double-drive setups.
Comparison to Other Solutions
- Butt/Box vs. Arm Hinges: Butt/box hinges carry the leaf on the hinge collar for a smooth, supported swing; arm hinges are paired male/female sets typically used when a 180° swing is required by design.
- Malleable vs. Pressed Steel: Malleable steel castings provide robust, serviceable hardware for heavy leaves; pressed steel versions are common where lighter loads or budget constraints apply.
- 90° vs. 180°: Standard butt/box hinges swing 90°; adding a 180° adapter extends the arc without reworking the opening.
Installation
Place the large hinge body around the gate post and secure with the included bolts and nuts. Remove the collar end and wrap it around the 1-5/8″ or 2″ gate upright. Set the gate so its horizontal rails bear on the hinge for smooth operation (often requires a short extension at the bottom of the vertical upright). Position the lower hinge just above grade and allow the leaf to travel within the collar’s circumference. If needed, add a hinge bearing plug between collar and frame to reduce wear.
