Fence Gate Hardware Guide: Hinges, Latches, and Drop Rods
Gate hardware count comes down to two things: how many gate leaves you have, and how wide each one is. This small detail is easy to underestimate — a gate that sags within its first year is often traced back to insufficient hinge support for its width. This guide covers the standard rules for hinges, latches, and the extra hardware double gates require.
Hinges Scale With Gate Width
Every leaf needs its own set of hinges, and a leaf under 4 feet wide typically holds fine on 2 hinges. Anything wider needs a third hinge to stop it from sagging over time — the extra weight and leverage of a wider leaf puts more stress on the top hinge in particular, which is usually the first to fail on an under-hardwared gate.
Single vs. Double Gates
A single gate needs one set of hinges plus a latch. Double gates (two-panel openings) add a wrinkle: one leaf is usually active (with the latch) and the other is passive, held by a drop rod or cane bolt into the ground or a header. Double gates need a drop rod that single gates don’t, since the passive leaf has no latch of its own to keep it from swinging.
Why the Drop Rod Matters
Without a drop rod, the passive leaf of a double gate has nothing holding it in place except its connection to the active leaf through the latch — which puts uneven stress on the hardware and can work the passive leaf loose over time. The drop rod locks into a sleeve set in the ground (or a header above, for gates with an overhead frame), keeping that leaf steady while the active leaf opens and closes independently.
Worked Example
1 single gate (4 ft wide) + 1 double gate (widest leaf 5 ft).
Single gate: 4 ft leaf → 2 hinges + 1 latch.
Double gate: 5 ft widest leaf → 3 hinges per leaf × 2 leaves = 6 hinges, 1 latch (active leaf), 1 drop rod (passive leaf).
Total hardware: 8 hinges, 2 latches, 1 drop rod.
Common Mistakes to Avoid
- Using only 2 hinges on a gate leaf wider than 4 feet, leading to sagging over time.
- Forgetting the drop rod on a double gate’s passive leaf.
- Assuming both leaves of a double gate need a latch, when only the active leaf typically does.
- Not accounting for extra hardware weight capacity needed on solid privacy panel gates versus open picket gates.

Frequently Asked Questions
How many hinges does a wide gate need?
Gate leaves up to 4 feet wide generally need 2 heavy-duty hinges. Leaves wider than 4 feet, or gates carrying extra weight like solid privacy panels, should use 3 hinges to prevent sagging.
Do double gates need extra hardware beyond hinges and a latch?
Yes — double gates need a drop rod (also called a cane bolt) on the inactive leaf so it can be locked into a sleeve in the ground or a header, keeping that leaf steady while the active leaf opens and closes.
