Recessed In Sheet Rock Wall
Find Stud Cut Out Sheet Rock
This wall is an outer wall of the garage. Most are not insulation (at least in Texas). Check first to make sure it is not insulated. Once sheet rock is cut out, save it to use as your back board.
Re-use sheet rock
Nail a 1×4 to the studs and set your sheet rock cutout on top of it as shown. Then install your EZStudRacks.
It’s time for the next cutout
You can always change your shelves at anytime. When you are ready, cutout the next section along the studs and repeat.
This video shows how you can notch out your sheet rock wall in under 10 minutes. Sorry about the quality, I hope to redo it soon. The concept is pretty easy to do.
