Molding

One Sided Reducer- More common uses against solid objects such as sliding doors or other areas where common quarter round would not look proper. Vertical height flush reducer from material to other floor coverings such as vinyl and carpeting.

Baby Threshold- Also used at sliding door areas. This is the most versatile trim piece I've found that can be adapted with the use of a table saw for floor coverings that have a slight vertical height difference. 

T Molding- Used to transition one floor covering to another, typically ceramic tile with the same vertical height.

Overlap Reducer- Commonly used for floating floors or engineered products over 1/2" in thickness that transition to other floor coverings of lower vertical height. Carpet, ceramic tile, and vinyl are examples. Not all manufacturers make this threshold.

Stair or Bull Nosing- Used for step construction when using plank or strip.

Baseboard- Installed against the drywall or plaster board.

Quarter Round or Shoe molding- Installed after the floor against existing baseboard to allow proper expansion space.
