Simple french cleat frame hanger

For my home theater, I needed hangers to attach large frames to the walls.

However, I also wanted the frames to be easy to remove for maintenance purposes.

That's why I designed these simple french cleat hangers.

They are 8mm thick.

There are 2 versions.
1. with a normal screw hole
2. with a slotted hole to make it easier to adjust the position

For one hanger you need 2 pieces.
