A French cleat can safely hold anywhere from 30 kg to 180 kg, depending on cleat type, length, wall material, screw quality, and installation. Test data shows:

• 152 mm Type A: 30 kg

• 152 mm Type B: 40 kg

• 1220 mm Type A: 135 kg

• 1220 mm Type B: 180 kg

*Real‑world capacity may be lower if the wall or fasteners are weaker than the cleat itself.

The maximum safe load of a French cleat is determined by four interacting factors

• Wall Material (Critical). 
• Screw Type and Installation (Critical)
• Lever Arm Distance (how far the centre of mass projects from the wall)
• Aluminium Strength

Installation Overview

Split batten (French cleat) system is designed for the concealed fixing of panels, signage, or mirrors to walls. It allows for a clean, flush finish with no visible screws, making it easy to both install and remove the panels when needed.

Step-by-Step Installation

1. Separate the Pair: Each set requires two interlocking aluminum pieces—one section mounts to the wall, and the matching section attaches to the back of your panel.

2. Mount the Wall Rail:

• Position one of the rails against your wall at the desired height, ensuring it is perfectly level.
• Secure it into the wall studs or appropriate wall anchors using the provided screws.
• Tip: Make sure the interlocking lip of the rail is facing upward and outward from the wall.

3. Attach the Panel Rail:

• Line up the second rail on the back of the panel or item you want to hang.
• Secure it firmly into place using the included screws.
• Tip: Make sure the interlocking lip on the panel is facing downward and inward so it can drop into the wall mount.

4. Hang the Panel:

• Lift your panel slightly above the wall mount and lower it into place.
• The two low-profile sections will interlock seamlessly, holding the panel securely against the wall with a minimal, concealed gap.
