Unfinished Knotty Alder Full-Lite Barn Door, 42 x 84 in

A natural knotty alder sliding barn door with frosted full-lite glass delivers privacy and light in one elegant slab. Unfinished wood lets you stain to match your décor, and the solid-core construction adds durability and authentic heft.


Key Features:

  • Ready to Stain: Natural unfinished knotty alder accepts custom finishes to match any interior.
  • Privacy + Light: Frosted full-lite pearl glass obscures views while brightening rooms.
  • Solid-Core Construction: Provides durability, sound reduction, and an authentic wood feel.
  • Slab-Only Design: Use with your preferred barn door track and hardware (not included).
  • Trim Allowance: Up to 2 in height (bottom rail only) and 1/2 in width total; trimming beyond voids warranty.

Frequently Asked Questions (FAQ):

Q: Does this door include the track and hardware?
A: No. It is a slab-only door; barn door track and hardware are sold separately.

Q: Is the glass see-through?
A: The frosted pearl glass is highly obscured (privacy rating ~9/10), providing privacy while allowing light.


Q: What openings will a 42-in wide barn door cover?
A: Typically covers 32.5–36.5-in openings depending on casing and installation.


Q: Is the door handed?
A: Universal handing; it works for left or right sliding configurations.
