Details & specifications.

From the maker · Masonite’s description

Elevate interiors with a solid-core knotty alder barn door featuring frosted Pearl glass for light diffusion and privacy. The natural, unfinished slab arrives ready to stain and installs on a sliding track for space-saving transitions in pantries, laundry rooms, closets, and baths.

Alder Warmth Meets Soft, Silhouetted Light

This barn door marries knotty alder’s organic texture with satin-frosted panels that bathe rooms in a gentle glow. The refined 3‑lite symmetry creates a crisp architectural rhythm that feels tailored yet inviting. Style it with matte-black hardware and layered neutral textiles to balance rustic character and contemporary polish. It’s a quietly luxurious statement that reshapes passageways into moments of design.

Transform your entry with timeless alder and privacy glass—choose this Masonite barn door and elevate your space today.

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.
