Self-closing gate
A gate fitted with spring hinges or a closer that returns it to the closed position on its own, from any open position, with nobody touching it. On a pool barrier this is not an upgrade — the adopted code requires the gate to close and latch by itself, and the inspector tests it.
The phrase that decides the inspection is "from any open position." A gate that swings shut from wide open but stalls when it is opened a few inches has failed, and so has a gate that closes but arrives too slowly or too weakly to throw the latch. Both are common, and both are usually a tension problem rather than a hardware problem — spring hinges are adjustable, and they have to be tuned to the leaf actually hanging on them rather than left where the factory set them.
The other frequent cause is the ground. A gate that binds on a high spot at one point in its arc stops there, and a gate hung on a post that has moved out of plumb pulls itself out of square as it swings. Both put the latch somewhere other than where the catch is. This is why gate posts on a pool enclosure get set as terminal posts, deeper and heavier than the line posts, and why the swing is walked from every position before the crew leaves.
Direction is part of the requirement as well: a pool barrier gate opens away from the pool, so it closes against its own stop instead of being pushed open by someone leaning on it. Which edition of the code applies to a given property, and whether the township or borough has amended it, is decided by the municipality enforcing it — so the hardware schedule gets confirmed with that code office before anything is ordered rather than carried over from the last job. Weight is worth planning for too. A heavy solid wood gate is the hardest thing to keep self-closing over time, because wood gates settle and rack; a welded aluminum frame holds its geometry and keeps the closer working.
