Wall mount racks are designed to be attached to the wall. Wall mount racks are best for light installations where space is limited. The biggest advantage is that it can save floor space and is suitable for areas where other racks cannot be installed. Typically, wall mount racks are ideal for applications containing equipment smaller than 800 mm or 31.5 inches, no larger than 22U, and/or weighing less than 130 kg or 286 lbs.
2-post wall racks are a popular choice for lighter installations, as wall racks can often handle the weight while saving floor space.
Although wall mount racks are usually designed to fit the US standard 16" drywall stud spacing, it is important to look at the racks of interest and make sure the racks are designed to fit your needs. The decision to mount the rack to the wall via drywall studs or wood screws can be influenced by the type of drywall you apply.

Floor racks are designed to be on the floor, as the description suggests. Floor racks are ideal for applications with unlimited footprints or applications that require more functionality than wall mount racks can provide. When comparing floor-standing racks to wall-mounting racks, floor-standing racks typically have higher weight capacity, deeper installation depths, and additional features such as leveling feet and mobile casters.
