Sizing Guide

Sizing For A Single Barn Door

Multiply your door width by two to get the correct track length.

Example: For a 3' wide barn door, you'd need a 6' barn door hardware kit.

If your door requires a track length that falls between sizes, you can round up to the next size and add the adjustable end stop. This will allow you to choose where the doors tops on the track. We are also able to cut tracks to your specifications.

For custom track lengths, call us at (253) 853-3815.
