Installation Tips

1. Find Your Studs

Use a quality stud finder to locate and mark all studs. French cleats must be screwed into studs for proper weight support. Mark the stud locations clearly before starting installation.

2. Cut at 45 Degrees

Set your table saw blade to exactly 45 degrees. Cut the cleat strips down the middle to create interlocking pieces. The angled cuts on wall cleats should face up; accessory cleats face down.

3. Level is Critical

Start with your first cleat perfectly level at the top. Use a 4-foot level or laser level. Every subsequent cleat will reference this first one, so accuracy here matters most.

4. Screw into Studs

Use 3-inch construction screws driven into every stud the cleat crosses. Pre-drill to prevent splitting. Two screws per stud (top and bottom of cleat) provides maximum strength.

5. Use Spacer Blocks

Cut a spacer block to your exact cleat spacing. Use it to quickly and accurately position each cleat as you work down the wall. This ensures consistent spacing throughout.

6. Seal the Plywood

Consider sealing or painting cleats to prevent moisture absorption and swelling. This is especially important in garage workshops. A coat of shellac or polyurethane works well.

Frequently Asked Questions

A properly installed French cleat can hold 50-75 lbs per linear foot when screwed into studs. A 4-foot cleat spanning 3 studs can easily support 200+ lbs. The key factors are: using 3/4" plywood, securing into studs with 3-inch screws, and distributing the load across multiple cleats. For very heavy items, use longer cleats that span more studs.

Standard spacing is 3-4 inches between cleat centers. Closer spacing (3 inches) offers more flexibility for mounting items at various heights but uses more material. Wider spacing (4 inches) is more economical and still works well for most storage needs. For tool walls with many small items, 3-3.5 inch spacing provides the most versatility.

French cleats are always cut at a 45-degree angle. This creates an interlocking hook system where the wall cleat and item cleat fit together securely. On wall-mounted cleats, the angled cut faces up (toward the ceiling). On accessory cleats attached to your items, the angle faces down to hook over the wall cleats.

While 1/2" plywood can work for very lightweight items (under 10 lbs), 3/4" plywood is strongly recommended for all French cleat systems. The thicker material provides: more bearing surface on the 45-degree cut, greater strength under load, less risk of splitting at screw locations, and a more stable mounting surface. The small extra cost is worth the durability.
