This is a parametric hanging box light. It is not ceiling based but you can change the elevation of the light and the length of the cables so that they'll go up to the cieling. You can also change the width, length and materials.

This is a ceiling opening vent with simple rectangular bars across, based on the one on the ceiling I was modeling. It is very parametric. You can change the width and length of the vent, the width and distance bewteen bars, trim width and bracing depth.

This is a parametric railing made out of metal piping, although you can change the material. You can choose whether the middle railing exists. You can change the length, height, diameter of piping, distance from the end supports to the middle supports, and how many middle supports to get it just how you like. It is face based so you can put it anywhere

I saved a couple diameters and materials for you but you can make your own.

Parametric Anchor bolt detail family. The bolt below the base plate is optional. Rod diameter, Projection above base plate, base plate thickness, etc. are all parameters. Embed Depth is an instance parameter. 

The pictures on the right are of the same family with different parameters. The picture on the left is how I used it. (That's why there is a grout thickness parameter. That's how embedment is measured.)

Here is a parametric nut detail item for you. I couldn't find this in the imperial library, so I made one. You input the Rod Diameter and all the rest of the dimensions update. There is an optional masking region and optional washer (instance parameters). 

The dimensions are all based on the proportions of a nut for a 1-inch rod. The height of the nut is equal to the diameter of the rod. The washer is always 1/8" wider than the nut. I know actual nut and washer dimensions don't scale perfectly from that, but this worked for my purposes. If you need precise dimensions, you could just edit the family, take out the equations for the parameters and put in dimensions manually to save your types. 

Just beware if you do that, DIM2 and DIM3 need to be correct or the arches will mess up. I'd measure that first (in proportion to Rod Diameter) Before you changed them.

Two metal wall mounted shelves. You can change the width, depth and space between them. You can also change how far the supports extend down and up.

Be aware that the elevation constraint measures from the bottom of the wall support, not the first shelf, so you might have to do some math.

Fully parametric. You can change the width, height, depth, number of shelves, and trim width, and the materials. 

the difference between this and the other one is that you can choose how many shelves you want.

A simple model of the glass fire case shown to hold a fire extinguisher or hose (not in the model). It's parametric, so you can change the width, height, and depth. It cuts from a wall. 

I suppose you could use this glass case for other purposes too.

This is a lot like the parametric wall vent except ceiling based, and improved. Now you can change the thickness, depth, and rotation of the louvres as well as how many louvres you want so you can get the right spacing. The vent dimensions, trim, and materials are also parametric.

Simple Cylinder detail item.

Length and diameter are parameters. Option of a line, empty, or infinite on the end. (Picture shows the different visibility parameters.) Masking or not is also a parameter. 

This was used for deep foundation details but could have many applications.

A simple ceiling light, based on a 6" x 6" one. However, you can change just about everything about it: width, length, depth of bracing, thickness and width of trim, and the materials. So it doesn't have to be square or small. The light source changes size according to your dimensions. The glass looks gray because it is not rendered.
