Installion Guide and Tips
All the hardware are included with the package already. But there are somethings you may need to pay attention to.
1. You will need an electric drill, screwdriver and also a level ( I personally download one from mobile application)
2. Drill hole for anchors and screws, which is easy
3. The shorter nail is about 15mm long. The aluminum cleats are 3mm thick. So there are 12mm ( 0.47") of the nail will go into the frame or the thing you need to hang
4. This example is best to direct downward pressure. If you want to hang or mount a small shelf. I strongly recommend a longer nail

Effeicient - 4 inch cleat can supports up to 50 pounds, you can install 2 mount for more secure mounting
Good Inter-locking - Leave no gap between cleats so you can hang a light shelf. Very nice for wood wall decoration.
Highly Flexible - You can change your design easily, create a new look wall art for home from time to time. The cleats are reusable
Multi Purposes - It can use for picture frame or mirror mounting, or a tools caginet for garage. You can take it out and put it back in seconds
All in One - This set include not only 4 pairs aluminum alloy made Z clips, but also all fastening hardware for installations, all you need is drill and screwdrivers
