Up and Down Garage Doors explains hinge numbering, gauge thickness, and section placement so Metro Vancouver homeowners can identify the right parts for safe, balanced door operation.
Garage Door Hinge Numbers Explained — Why Hinges Are Numbered 1 Through 5+
Residential sectional doors use graduated hinges because each section sits at a different radius as the door curves from vertical track to horizontal track. Hinge #1 mounts on the bottom section where the track is nearly vertical; #2 on the second section; #3 on the third; #4 on the fourth; #5 (and sometimes #6) on the top sections where the track is horizontal. The number corresponds to the offset between the roller carrier and the leaf that bolts to the section — higher numbers have greater offset to match the tighter curve.
Gauge Thickness and Wire Diameter
Standard residential hinges are 14-gauge (≈0.075 in / 1.9 mm) or 13-gauge (≈0.090 in / 2.3 mm) galvanized steel. Heavy-duty 11-gauge (≈0.120 in / 3.0 mm) hinges appear on commercial doors or oversized residential doors over 16 ft wide. The roller stem is typically 7/16 in (11 mm) diameter for 2 in rollers; 11-gauge hinges often use 1/2 in stems for 3 in rollers. Cycle ratings follow DASMA 102: residential hinges are tested to 10,000–25,000 cycles; commercial-grade to 100,000+ cycles.
Placement Per Section
Typical 7 ft high door (four sections): bottom section = #1 hinges at each end; second section = #2; third section = #3; top section = #4 (or #5 on heavier doors). An 8 ft door (five sections) adds a #5 hinge on the top section. End hinges carry the roller; center hinges (no roller) use the same numbering but without the roller carrier. Always match the hinge number stamped on the leaf — mixing numbers changes the door’s pitch and binds the rollers.
Metro Vancouver Climate Impact on Hinges
Coastal humidity accelerates galvanizing breakdown; white rust appears within 2–3 years on uncoated 14-gauge hinges in Richmond, Delta, and South Vancouver. Salt air near Tsawwassen and White Rock reduces hinge life to 5–7 years unless upgraded to powder-coated or stainless roller stems. Winter freeze-thaw cycles swell wooden door frames, shifting hinge alignment and causing premature roller wear — inspect hinge bolts annually after the first hard frost.
Common Hinge Part Designations
DASMA standard stamps: “14-1”, “14-2”, “14-3”, “14-4”, “14-5” for 14-gauge; “13-1” through “13-5” for 13-gauge; “11-4”, “11-5” for 11-gauge. Major manufacturers (Ideal, D& D, National) use the same numbering. Center hinges marked “C” (e.g., “14-3C”). Always replace with identical gauge and number; upgrading gauge without matching offset creates binding.
FAQ
Can I replace a #3 hinge with a #4 hinge if that’s what I have on hand?
No. The offset difference changes the roller’s track position, causing the door to bind or gap at the seals. Use the exact number stamped on the original hinge.
How do I know if my door needs 13-gauge instead of 14-gauge hinges?
Doors over 16 ft wide, doors with 3 in rollers, or doors rated for 25,000+ cycles typically specify 13-gauge. Check the manufacturer’s label on the door’s interior stile.
Why do my hinges squeak every winter?
Cold temperatures thicken lubricant and contract metal clearances. Apply a PTFE-based spray (not WD-40) to roller stems and hinge pivots each November.
Are stainless steel hinges worth the cost for a White Rock oceanfront home?
Yes. Stainless roller stems and powder-coated leaves last 15+ years in salt air versus 5–7 for standard galvanized — cost is roughly 2.5× but eliminates annual replacement labor.
What’s the difference between an end hinge and a center hinge?
End hinges include a roller carrier; center hinges do not. Both share the same number/offset. Order the correct type for each position.
