Quarter Round Unfinished Red Oak Trim is great to finish out your flooring project. Quarter round is exactly as its name implies. It is a quarter of a round dowel. A 90-degree angle on the backside with a perfect quarter radius on the showing side. Quarter round helps cover gaps in your flooring between the wall and floor. It works great on solid hardwood, engineered hardwood, laminate, tile, and vinyl flooring. Why use coordinating trim that cost way too much. Coordinating trim is just what it sounds like. It doesn’t quite match, it coordinates. Unfinished quarter round is great if you are going to Stain it to match trim you already have or flooring you are installing.
