From the maker · Masonite’s description

Transform any room with this solid-core Knotty Alder sliding barn door kit from Masonite. The unfinished Z-Bar design brings rustic warmth while the included black hardware and track deliver smooth, space-saving operation.

Rustic Warmth, Effortless Movement

This Z-Bar barn door infuses a room with organic texture—its knotty alder grain feels bespoke and beautifully grounded. The bold diagonal brace becomes a graphic statement, juxtaposed with sleek black hardware for a modern-rustic balance. Finish it in a smoky stain for drama or a light wash for airy charm, then let it glide to reveal hidden storage or a serene ensuite. It’s a simple switch that delivers high-impact, luxurious livability.

Elevate your space with rustic style and smooth, space-saving function—add this Masonite barn door kit to your project 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.
