Description
The Std Hinge #3 – 14Ga is a heavy-duty sectional overhead door end hinge manufactured from 14-gauge steel for reliable panel articulation and correct roller positioning.
Designed for standard sectional garage and overhead door systems, the #3 hinge is typically installed between the third and fourth door sections at the left-hand and right-hand end stile positions.
The #3 hinge provides a greater roller offset than the lower-numbered #1 and #2 hinges, helping maintain the correct relationship between the upper door panels and the vertical track as the door travels towards the curved track.
🚪 Sectional Door End Hinge
The #3 hinge performs two important functions within a sectional overhead door:
- Connects the third and fourth door sections
- Supports and positions the track roller
The hinge pivot allows the adjoining panels to articulate while the roller carrier maintains the required roller position relative to the door.
3️⃣ #3 Hinge Position
The #3 designation identifies the hinge position and roller offset within a standard numbered sectional door hinge arrangement.
A #3 hinge is typically installed:
- Between the third and fourth door sections
- At the left-hand end stile
- At the right-hand end stile
The sections are counted upwards from the bottom of the door.
🔩 Heavy-Duty 14-Gauge Steel
The hinge is manufactured from:
- 14-Gauge Steel
This heavy-duty construction provides a strong connection between adjoining door panels while supporting the track roller during operation.
14-gauge hinges provide excellent durability for residential, commercial and custom sectional overhead door applications.
🛞 Standard Roller Compatibility
The #3 hinge incorporates a roller carrier designed to accept a standard sectional door roller.
Typical roller compatibility:
- 7/16″ Diameter Roller Stem
The roller stem passes through the hinge’s roller carrier while the roller wheel runs within the sectional door track.
📐 Increased Roller Offset
Numbered sectional door end hinges progressively increase the roller offset as the hinge position moves higher up the door.
A typical arrangement progresses through:
- #1 Hinge
- #2 Hinge
- #3 Hinge
- #4 Hinge
The #3 hinge positions the roller further away from the door than the #1 and #2 hinges.
This progressive offset helps maintain the correct relationship between the door panels and the track.
⚙️ Correct Door Alignment
Using the correct numbered hinge is important for maintaining proper sectional door geometry.
Correct #3 hinge positioning helps provide:
- Correct roller alignment
- Consistent panel positioning
- Smooth vertical movement
- Smooth transition towards the track radius
- Reduced binding
- Reduced panel rubbing
- Reduced roller wear
- Reduced track wear
Installing the wrong numbered hinge can position the roller incorrectly and cause the door to bind or run poorly.
🔄 Smooth Panel Articulation
The hinge pivot allows the third and fourth sections to change angle relative to one another as the door moves through the track system.
This articulation is particularly important as the upper sections approach and travel through the curved portion of the track.
A correctly installed hinge should move freely without excessive play, distortion or binding.
🏗️ Suitable for Sectional Overhead Doors
The Std Hinge #3 – 14Ga is suitable for compatible sectional overhead door systems using conventional numbered end hinges.
Typical applications include:
- Residential sectional garage doors
- Aluminium-framed sectional doors
- Custom sectional doors
- Commercial sectional overhead doors
- Replacement sectional door hardware
- New sectional door manufacture
The hinge arrangement should always correspond with the door’s panel construction and track geometry.
🔧 Replacement Hinge
The #3 hinge can be used to replace a worn or damaged hinge of the same type and position.
Hinges should be inspected for:
- Cracking
- Bent or distorted steel
- Excessive pivot wear
- Elongated mounting holes
- Corrosion
- Loose fasteners
- Damaged roller carriers
- Abnormal roller movement
A damaged hinge can affect both panel alignment and roller position and should be replaced before further damage occurs.
🛠️ Installation
The #3 hinge mounts to the end stile between the third and fourth sectional door panels.
During installation, check:
- Correct #3 hinge position
- Roller condition
- Roller stem compatibility
- Roller-to-track alignment
- Panel alignment
- Hinge movement
- Mounting fasteners
- Track clearance
The roller should move smoothly within the track without binding or excessive sideways movement.

⚠️ Please Note
This product is one Std Hinge #3 – 14Ga unless otherwise specified.
Roller and mounting fasteners are not included unless specifically stated.
The #3 hinge is typically installed between the third and fourth door sections at the left-hand and right-hand end stile positions.
Do not substitute a #1, #2, #4 or other numbered hinge solely because it appears physically similar. Each hinge number provides a different roller offset, which affects the position of the sectional door within the tracks.
When replacing a damaged hinge, inspect the corresponding roller, track and adjoining panel hardware for wear or damage.
Garage doors contain components operating under significant spring and cable tension. Do not loosen or remove bottom fixtures, lifting cables, spring assemblies or other tensioned components unless appropriately trained and equipped.
