Build a French cleat wall system for modular tool storage

Install interlocking 45-degree beveled strips (French cleats) on a wall, then hang custom tool holders, shelves, and bins that hook onto the cleats. This creates a fully modular, reconfigurable wall storage system that can be rearranged as your tool collection changes.

How It Works

A French cleat is a strip of wood (typically 3/4-inch plywood or a 1x4 board) ripped lengthwise at a 45-degree angle. One half mounts flat to the wall with the bevel facing up and out. The matching half attaches to the back of a tool holder or shelf with the bevel facing down and toward the wall. The two bevels interlock by gravity, creating a strong, instantly removable hook. Install horizontal cleats every 4-6 inches up the wall, and any holder can go anywhere.

Step-by-Step

1. Rip 3/4-inch plywood strips about 3 inches wide at a 45-degree angle on a table saw
2. Mount wall cleats horizontally to studs using screws, spacing them 4-6 inches apart vertically
3. Use a level to ensure each cleat is perfectly horizontal
4. Build tool holders from scrap plywood: attach the mating cleat strip to the back of each holder
5. Hang holders on the wall by hooking the bevels together
6. Add holders for specific tools: drill holsters, screwdriver racks, wrench organizers, shelf boxes

Tips

• A table saw makes cutting cleats easy and consistent; a circular saw with a guide works too
• Paint or seal the cleats to prevent warping in damp garages
• 3/4-inch Baltic birch plywood is ideal: strong, flat, and holds screws well
• Each cleat can support 50+ pounds when mounted into studs
• You can buy pre-made French cleat accessories from companies like Wall Control, or build your own
• This system is superior to pegboard for heavy tools because the wood-to-wood interlock is far stronger than pegboard hooks
• Dozens of free plans for French cleat tool holders are available on YouTube and woodworking forums

Common Mistakes

• Not hitting wall studs: cleats must be screwed into studs for adequate strength
• Making the bevel angle too shallow or too steep: 45 degrees is the standard for a reason
• Spacing wall cleats too far apart: 4-6 inches gives maximum flexibility for holder placement
