Aligning Gate Latches and Drop Rods

Nothing about a well aligned latch draws attention, which is the whole point. The notes at gate installation georgetown inside michigan politics treat latch work as the last real step of a gate installation in Georgetown, TX, because a gate that hangs true can still be a nuisance if the bolt only catches on a good day.

Where does the latch go?

The latch sits at a height a person can reach without bending, usually thirty-six to forty-eight inches, and clear of the pickets so fingers cannot be pinched. The keeper is welded or bolted to the latch post so that it lines up with the bolt when the leaf is at rest. The gate is held closed, a pencil mark is made through the bolt hole, and the keeper is set to that mark.

How much play should the latch have?

A latch with a quarter inch of play at the bolt will still catch in August, when the steel has grown, and in January, when it has shrunk. A bolt that fits snug in July binds in winter. Slotted keepers and adjustable strike plates give that play, and a frame in full sun around Georgetown Square moves more than one in shade.

What is a drop rod for?

A drop rod is a steel pin that falls into a hole in the ground and holds one leaf of a dual swing gate shut. The hole is lined with a sleeve of pipe set in concrete, with a drain at the bottom so water and limestone dust do not pack it solid. The rod is cut so its tip clears the sleeve with an inch to spare when the gate is open, and it drops a full four inches when closed.

How are the two leaves lined up?

On a dual swing pair, the first leaf is set to its drop rod, and the second leaf is brought to meet it at the center. A center stop or a rubber bumper keeps the leaves from swinging past each other. Both pickets or rails at the meeting edge should line up the way they would on a fence panel, and a gap that tapers is a sign that one hinge post has leaned.

What if it still does not close cleanly?

A latch that misses means that something else is moving. The usual causes are a hinge that is a hair low, a post that settled in clay, or a leaf that has sagged at the free end. The latch is adjusted last, after the hinges and the posts have been cleared, since a latch tuned around a moving frame is just a delayed service call.

A closing test with a gentle push from the open position settles the question. The bolt should drop home on its own weight without a slam.
