Can I Have A Standard Car Please?

A standard car, what's that? There's no such thing as a standard car, they're all different.
Welcome to hardware 101. The term standard should almost be obsolete in the hardware world because there are very few things that are standard in the industry.

I'm going to discuss door hardware and the options that are available so when you're ready to order you'll be armed with information. On a door there are typically hinges and a lock of some sort. "How many options could there be?" you say, on door hinges for a typical home you have to choose which finish you want, what size you want, and what type of corner you need.

Finishes are pretty easy to figure out, but for the corners you have 3 choices. The self explanatory choice would be square corner, the second choice is a 1/4in. radius, and the last choice is a 5/8in. radius. Here is a drawing that depicts all three options.

Also, a quick easy way to determine your radius is to hold up a dime and a quarter to the corner and see which one fits the best.

On the door locks, it gets a little more complicated. You have to choose which function you need. The different functions for interior doors are Privacy (there is a push button on the inside of the door that allows you to lock it,) Passage (the knob or lever turns but does not lock,) and a Dummy (the knob or lever does not move at all, and it gets screwed onto the face of the door.) Not only do you have to choose the function, but on the locks that move you have to choose the backset. A backset is the measurement of the distance from the edge of your door to the center of the bore hole that your knob or lever goes into. The most common backsets in the US are either 2-3/8in. or 2-3/4in. Here is a diagram to show you where to measure.

For exterior doors the functions are a Keyed knob or lever (there is a key built into the knob or lever and a push/turn button on the inside,) a Single Cylinder Deadbolt (a key on the outside and a turn knob in the inside,) and a Double Cylinder Deadbolt (a key on both the outside and the inside.)

Another option that you will need to know would be the door handing, the easiest way to determine handing is to stand on the outside of the door and look at the hinges. The key is to always be on the outside, if the hinges are on the Right you would order a right hand lock and if the hinges are on the Left you would order a left hand lock. This honestly is the easiest way to figure it out. Many people use different methods, and tell you that the direction the door swings matters but I think it only makes it more complicated.

Last would be door thickness. A "standard" door- scratch that, a "typical" residential door is either 1-3/8in. or 1-3/4in. thick. All residential locks come equipped to fit either of those sizes. Occasionally, you'll have an entry door that will be thicker and some manufacturers make a thick door kit to accommodate those.
