Hanging a Leaf and Setting Clearance

Hanging is the stage where all the earlier measurements are cashed in, and three separate gaps get decided in about twenty minutes. The hanging notes at Metal Gate Installation Mount Pleasant, SC highlandahs list them in the order they have to be set, since a Mount Pleasant metal leaf hung with the ground gap right and the hinge gap wrong will not close a month later.

The Three Gaps

The hinge gap sits between the leaf and the hinge post and is set by the hardware. The latch gap sits between the leading edge and the far post and takes up thermal movement and future sag. The ground gap runs underneath and has to hold through the whole swing. Each is small, and each one being wrong produces a different complaint.

Ground Clearance Is Not Constant

A swing leaf sweeps an arc, so the ground under the whole arc matters, not just at the closed position. Set the clearance at the tightest point in the sweep and check it at the fully open position too. A driveway that rises across the arc is why a gate can be perfect when shut and grounding when open.

Allow for Settlement

Everything drops slightly in the first year. Hinges bed in, footings settle, and the leaf takes up any slack in its own frame. Setting a ground clearance at the absolute minimum on day one guarantees a scraping gate by the following summer, so a little extra is deliberate rather than sloppy.

Blocking It Up

The leaf is supported on packers at the correct height and checked for level and for square before any hinge is finally tightened. Trying to hold a heavy gate by hand while marking hinge positions is how leaves get hung a quarter of an inch out, and a quarter of an inch at the hinge is much more at the latch.

Check Before the Hardware Goes On

With the leaf blocked in position, confirm the top rail is level, both gaps are even down their length, and the latch will meet its keeper without being lifted. Once the hinge is welded or bolted through, every one of those becomes a much longer conversation.
