How do I hang a piece of pallet wood on the wall over my window?

brackets one l on the wood and the other L on the wall.

I am sorry L is the shape of the bracket, they come in various sizes and there is a hole for a screw in each end, you could place one screw in one end and another in the other end and screw one to the wall and one to the piece of pallet wood.

Hello TK,

I would suggest the rail over the edge cleat locking system.

Here's some links to consider with the heavy weight of your pallet.

I hope this helps.
