We all love barn door anything, but the high cost of hardware can be prohibitive.  In this tutorial, I'll show you how we DIYed our own barn door hardware the absolutely least expensive way using all new off the shelf materials.  And it's pretty easy to make too, with just a drill and a jigsaw and some spray paint.

The barn door hardware is made up of two parts - the rail and the rollers.  The rail is attached to the cabinet.  The rollers are attached to the door and roll along the rail.

The Rail - Barn Door Hardware DIY

Let's start with the rail.

To make the rail track, simply use 1" wide flat metal bar, available at most any hardware store, for about $10 for six feet.  You'll need some leftover flat metal bar for the roller pieces too.  For our 4 foot wide project, I purchased a six foot long piece.

Using a drill bit designed for metal, drill holes to mount the flat metal bar to the cabinet.  Since we were using 1/4" bolts, we used a 1/4" drill bit to drill the holes.  You'll need to drill holes every two feet or so - we did three holes for a four foot wide cabinet.  Do place your holes where it makes sense in mounting to the cabinet.

The rail needs to be set off the cabinet so the door has room to pass.  You can find spacers at most any hardware store.  The spacer length should be equal to the thickness of your door panel - our door was 1" thick, so we used a 1" spacer.  

You'll also need washers, a bolt and locking nut.  We used 1/4" size.

For the bolt that attaches the rail to the cabinet, a flatter head is more desireable, so it doesn't cause the sliding door to catch.  If you can't find a flat head bolt, a round head will do.  And if you must use a hex head, just add some washers on your door rollers (see below) so the door can pass over the bolt head.

Rail Supply List

• 1" wide x 1/8" thick  Flat Metal Bar
• 1/4" bolt, 1" longer than cabinet header thickness plus spacer length
• Spacers, same length as door thickness
• 1/4" washers (get a few extra, you'll need them)
• 1/4" locking washers
• Jigsaw with metal blade
• 1/4" Drill bit for drilling metal

The Rollers - Barn Door Hardware DIY

The rollers are so simple!  Here's how we put them together -

We started with a piece of flat metal bar cut with a jigsaw 8" long.  We drilled three holes in each flat metal bar, one at the top for attaching the roller wheel, and two at the bottom for attaching the door.

The roller is made up of two 2" fender washers, with a 1/4" hole in the center.  In between the larger fender washers are smaller 1-1/2" fender washers.  We used three.

We placed washers on the outsides of the larger fender washers to prevent the wheel from rubbing on the bar and scratching paint off.

Finally, a 1/4" bolt, 1-1/4" long is the "axel" - all the parts are placed on the bolt and a locking nut holds it all on.  Leave the locking nut loose enough so the "wheel" can spin freely.

If you have a two minutes, I show you how to put this together in this video-

If this is at all confusing, the video will definitely clarify it all.

Roller Supply List

• 1" wide x 1/8" thick flat metal bar, cut to 8" lengths (two needed per door)
• 1/4" bolt, 1-1/4" long
• 1/4" washers (the same used for hanging the rail)
• 1/4" locking nut (the same used for hanging the rail)
• 2" x 1/4" fender washers
• 1-1/2" x 1/4" fender washers
• jigsaw for cutting flat metal bar
• drill with metal drill bit for drilling holes in flat metal bar
• You'll also need bolts or lag screws to attach the door to the flat metal bar - this will depend on your door thickness and construction
