Product Description
Bulldog Hinge — Pressed Steel, Galvanized, Professional Grade for Commercial Chain Link Gates
- Professional Grade: Pressed steel construction with a durable galvanized finish for long service life
- Smooth Operation: Gate rides on the hinge collar for consistent, repeatable swings
- 90° Standard Swing: Opens to 90°; compatible with 180° hinge adapters when a full fold-back arc is required
- Flexible Fit: Collar sized for 1-5/8″ or 2″ round gate uprights (see Specifications)
- Commercial Applications: Well-suited to barrier gates, panic-bar gates, large swing leaves, and double-drive layouts
This galvanized Bulldog hinge (pressed steel) is a proven, professional grade solution for commercial chain link gates. The post-side body clamps to the round post, while the collar wraps the gate upright so the leaf bears on the hinge—helping maintain alignment and a smooth swing through daily cycles. Out of the box, the hinge provides a 90-degree opening; where site logistics demand maximum clearance, pair each hinge with a 180-degree adapter to park the leaf along the fence line. With options for 1-5/8″ or 2″ uprights and multiple post diameters, it standardizes hardware across a wide range of jobs.
Why Choose This Bulldog Hinge
- Built for the field: Pressed steel body and galvanized coating for outdoor durability
- Consistent installs: Common round-frame sizes and post diameters for easy planning
- Scalable: Two hinges for most single leaves; add a third on tall or heavy gates
- Upgrade path: Optional 180° adapter extends the swing arc without changing the opening
- Low maintenance: Simple, serviceable design that’s easy to inspect and tighten

Installation
Place the hinge body around the gate post and tighten the supplied 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; position the lower hinge just above grade so the leaf tracks cleanly along the collar’s path. If needed, add a hinge bearing washer between collar and frame to reduce wear.
Buying Guide
- Match the post O.D.: Select the hinge size that fits your gate post diameter (see Specifications).
- Confirm frame size: Choose the collar size for 1-5/8″ or 2″ round uprights.
- Choose hinge count: Most single leaves use two hinges; consider a third for gates around 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.
Frequently Asked Questions
- What’s the swing range?
- 90° in either direction by default; add a 180° hinge adapter for a full fold-back swing.
- How many hinges should I use?
- Most single gates use two hinges; tall or heavy gates (around 8′ and up) typically use three.
- Which gate frame sizes does the collar fit?
- 1-5/8″ or 2″ round uprights (select the correct collar size).
- What gate types are these best for?
- Commercial chain link applications including barrier gates, panic-bar gates, large swing leaves, and double-drive gates.
- When should I add a bearing washer?
- If the collar shows signs of cutting into the gate upright; the washer helps distribute load and reduce wear.
Comparison to Other Solutions
- Bulldog vs. Butt/Box Hinges: Both are heavy-duty commercial solutions; bulldog (pressed steel) supports the frame under a collar, while butt/box hinges cradle the upright at the brace rail. Choose based on site preference and hardware package.
- 90° vs. 180° Swing: Standard 90° is fast to deploy; use a 180° hinge adapter where traffic patterns require the leaf to park along the fence.
