Garage Door Hinge 3 for Higher Roller Offset
- Number 3 end hinge for the next stage of the sectional door hinge sequence
- Higher dual roller-carrier offset than Garage Door Hinge 2
- Stamped “3” and “14-GA” identification for easier assembly sorting
- Galvanized steel construction with formed side supports and adjustment slots
- Carrier opening, spacing, hinge movement, hole location, and surface inspection
- Available with matched Hinge 1, Hinge 2, rollers, tracks, and complete hardware kits
- OEM thickness, hole pattern, finish, marking, and export packing options
Higher Number 3 Carrier Position
Garage Door Hinge 3 places the roller carrier higher than Hinge 2. Used in the approved numbered sequence, this progressive offset helps the upper door section keep the roller aligned with the track path as the connected panels move from vertical travel into the curve.
14-Gauge Steel and Formed Double Carrier
The standard sample is stamped 3 and 14-GA for quick model and gauge identification. Formed side supports, two parallel carrier tubes, elongated mounting slots, and a galvanized steel surface provide repeatable geometry for residential sectional door assembly.
Matched Numbered Hinge Sets
Gemax can supply Hinge 1, Hinge 2, and Hinge 3 as a matched sequence instead of mixed individual parts. Compatible rollers, tracks, brackets, cables, drums, springs, fasteners, and complete hardware cartons can be consolidated for one project.
OEM Inspection and Export Packing
Each batch can be checked for model marking, steel thickness, carrier height, opening diameter, parallelism, hinge movement, mounting-hole position, and coating condition. Counted inner packs, reinforced cartons, pallets, private labels, and mixed hardware kits are available for export orders.
Complete Hinge Range, Material Options, and Sample Approval
Gemax supplies a complete numbered hinge range with pre-galvanized steel, barrel zinc-plated steel, black powder-coated, spangle-galvanized, and heavy-duty material options. OEM thickness, hole patterns, carrier height, surface finish, stamping, labels, and export packing can be customized. Buyers may review drawings, photos, or a physical pre-production sample before confirming bulk production.

What Is Garage Door Hinge 3?
Garage Door Hinge 3 is a numbered end hinge used at a higher position in the progressive roller-hinge sequence of a sectional garage door. It connects adjacent door sections and supports the roller stem at the side of the panel. Compared with Hinge 2, the Number 3 carrier is positioned higher so the roller spacing can continue to follow the door and track geometry.
The exact installation position depends on the door height, panel layout, track system, roller stem, and manufacturer instructions. Buyers should confirm the stamped hinge number or provide a complete hardware schedule before ordering.
Garage Door Hinge 2 vs Garage Door Hinge 3
| Feature | Garage Door Hinge 2 | Garage Door Hinge 3 |
|---|---|---|
| Sequence position | Follows Hinge 1 in the numbered progression | Continues the progression after Hinge 2 |
| Relative carrier height | Intermediate offset | Higher roller-carrier offset |
| Identification | Stamped Number 2 on approved models | Stamped Number 3; this sample is marked 14-GA |
| Ordering method | Confirm the complete door specification and use matching approved hinges | |
14-Gauge Steel and Double Roller Carrier Construction
The photographed Garage Door Hinge 3 sample is marked 14-GA. Its galvanized steel leaves include elongated adjustment slots and formed side walls that support two parallel roller-carrier tubes. For consistent assembly, the carrier openings, tube parallelism, plate flatness, hinge movement, hole locations, and stamped markings must be controlled as one complete part.
Why the Numbered Hinge Sequence Matters
Numbered garage door hinges are not interchangeable only because their outlines look similar. The roller-carrier position changes progressively from Hinge 1 to Hinge 2 and Hinge 3. Using the wrong number can alter the roller location and panel-to-track relationship. Gemax can prepare matched numbered sets after reviewing the door dimensions, panel quantity, track type, and roller requirement.
Factory Quality Control for Garage Door Hinge 3
- Raw material and steel thickness verification
- Stamped model and gauge marking inspection
- Carrier height, opening diameter, and parallelism checks
- Mounting-hole and elongated-slot position checks
- Hinge movement and plate-flatness inspection
- Galvanized surface and visible defect inspection
- Batch counting, carton labeling, and export packing checks
OEM and Custom Supply Options
Garage Door Hinge 3 can be supplied in standard galvanized steel, bright zinc-plated steel, black powder-coated steel, or project-specific heavy-duty construction. OEM options can include steel thickness, mounting-hole pattern, carrier height, roller-stem compatibility, stamped identification, private labels, barcode cartons, and complete sectional door hardware kits.
Related Garage Door Hardware
Orders can combine Garage Door Hinge 1, Hinge 2, Hinge 3, additional numbered hinges, nylon or steel rollers, vertical and horizontal tracks, top and bottom brackets, cables, cable drums, springs, struts, seals, and fasteners. Consolidating compatible parts with one supplier simplifies model matching, documentation, and container loading.
Information Needed for a Fast Quotation
Please send the stamped hinge number, front and side photos or drawing, steel thickness, roller-stem size, track size, finish, order quantity, and packing request. For a matched hinge set, also provide the door width, height, panel quantity, application, and destination market.
Garage Door Hinge 3 is used at a higher position in the numbered end-hinge progression of a sectional garage door. The exact panel location depends on the door height, panel configuration, track system, and the door manufacturer’s installation instructions.
Hinge 3 has a higher roller-carrier position than Hinge 2. This continues the progressive roller offset needed as the numbered hinges move upward through the door assembly. The two models should be selected from an approved matched hinge schedule.
The photographed sample is stamped 3 and 14-GA, identifying the model number and nominal gauge specification. Steel thickness, material, coating, and tolerances should still be confirmed in the quotation or approved drawing for each order.
Yes. Gemax can supply matched Hinge 1, Hinge 2, and Hinge 3 sets together with compatible rollers, tracks, brackets, cables, drums, springs, fasteners, and complete sectional door hardware cartons.
