Retainer Moulding At Mars Lumber, you are not limited to the small selection of moulding profiles offered at home centers. Choose from over 1000 profiles, design your own custom profiles, or have us match unique mouldings already in your home. All mouldings are available in poplar, oak, cherry, maple & other woods. These hardwood selections will ensure that your project has crisp, durable & elegant mouldings. Historically, mouldings have often been pieced together to add complexity & detail. Also, the categories below are not strict. Most mouldings can be used for multiple applications. We will be happy to offer suggestions. Please contact us with your requirements.
