From the maker · Masonite’s description

Elevate interiors with this Masonite Traditional barn door crafted from solid-core knotty alder. The natural, unfinished slab is ready to stain and sized at 42 x 84 inches for a bold, space-saving transition between rooms.

Warm Modernity with Natural Alder Character

This barn door brings a soulful, organic presence—knotty alder’s warm grain wrapped in a crisp, five-panel rhythm. I love the quiet geometry; it anchors a room while letting textures sing. Stain it in a smoky walnut and pair with matte black hardware for a refined farmhouse moment, or keep it natural against soft gray walls for serene minimalism. It’s a chic essential that turns transitions into statements of luxury living.

Transform your doorway with solid-knotty alder style—add this Masonite barn door to your cart and complete the look with your favorite hardware.

Guide

What to measure before ordering

These notes are a planning aid. Product names, photos and shared descriptions do not confirm fit. Check the selected SKU, manufacturer specifications and installer measurements before ordering.

  1. 1

    Identify what you are replacing.

    A slab is the door panel. A prehung unit includes a frame. Record whether you need a slab or a complete unit, and check exactly what the selected product includes.

  2. 2

    Measure the opening and the frame.

    Record the width and height in several places, plus the wall or jamb depth. Keep rough-opening measurements separate from the existing door's dimensions. Include the units with every measurement.

  3. 3

    Confirm the swing and the exact model.

    Note which side the hinges sit on, the side you are viewing from, and whether the door swings toward or away from you. Confirm handing terminology and required clearances against the manufacturer's documentation for the selected SKU.
