The piece I ordered did not come ready to install, there was some slight modification I needed to do to make the latch handle fit in the steel box. Luckily I have the means to do so, but not everyone might. Also, the screws supplied with the steel box were the wrong thread pitch. Specifically, they were the kind of screws that go into a wooden door, not the steel lock box. I had to get new screws from the hardware store to make everything work right. Good product, but some assembly still required (more than advertised).
