Maximize space in a garage or workshop by installing extra shelving. Whereas traditional shelving leaves a footprint and takes up valuable floor space with its support legs, hanging shelves get their support from the ceiling and cannot be stumbled over or cumbersome. The following steps will explain how to install a 4×8′ hanging shelf in a garage.
The first step in building your hanging shelf is to mount the supports. If unable to locate the ceiling joists, use a stud finder to locate them. Cut 4 sections of 2x4 at least 30'' long to span the width of the ceiling joists. Determine where at least one corner of the shelf will end (against a wall) and make a mark on the ceiling for it. Measure 4' into the room from the mark and make another. Measure 8' along the length of the room from each of these two marks and place marks as well. Center your 2x4 sections over your mark so that they cover at least 2 ceiling joists and attach with the 4'' hex head wood screws. You should end this step with 4 ceiling blocks firmly attached making a basic 4x8 outline.
Use scaffolding, ladders, or other support structure to place the shelf at the desired height with one long end flush to the wall. Starting with one brace, bend it (at the base) a few inches out of perpendicular and away from the wall and attach to the shelf with 4'' hex screws. By bending the brace slightly, gravity will push the shelf tight to the wall and the shelf will not wobble. Using a level to make sure the shelf is perfectly even and connect the other three braces in the same way.
