Three Revit Families: All include standard sizes PLUS parametric dimensions for easy customization. All less than 312KB.
If you've tried to use manufacturer-supplied Revit families, you will appreciate the ones made by Yellowbryk. No need to manage multiple manufacturer model numbers to get the ones you need. These are parametrically driven so you can place the family and just change the Type to get a different size after it is placed.
The families even include named parameters for construction dimension. This enables easy customization without digging into the guts of the family in Revit's family editor.
