Do you need to transition from your new bamboo floor down to carpet, tile, or another lower floor? This reducer is just the molding you are looking for. It is milled with a groove down the back so you can slide it into the tongue portion of a flooring plank for a snug fit. We hand select the moldings to try and get the best match for your flooring. With that being said, once you get the molding, it is a good idea to go through a few boxes and select the plank you want to butt up against the reducer. That way you do not end up with a really light plank next to a dark reducer, or vice versa. See the above diagram for more details.
