French Cleat

French Cleat

Definition

A French Cleat is a strong and reliable hanging system for heavy framed objects or mirrors. Traditionally made of wood (but also available in metal), it consists of two interlocking bars: one beveled strip is securely mounted to the back of the frame, while the corresponding strip is anchored to the wall. When the frame is lowered into place, gravity and the angled cut cause the two bars to lock together, distributing weight evenly across the wall.

Uses

• Hanging heavy or oversized picture frames and mirrors.
• Securing art installations or gallery pieces that need long-term support.
• Mounting cabinetry, display panels, or architectural wall features.
• Providing a flush, professional appearance since the frame sits flat against the wall.

Best Practices

• Ensure both cleat halves are cut or purchased at the same bevel angle (commonly 45°).
• Attach the wall cleat into wall studs or use appropriate heavy-duty anchors for drywall or masonry.
• Confirm the frame cleat is securely fastened across the width of the artwork for stability.
• Check for level before final installation, as adjustments after mounting are limited.
• For very heavy pieces, use metal cleats rated for specific weight capacities instead of wood.
