1. You can place the compressor in the unit without attahing any of the isolators and simply slide anf tilt into place 1 boot at a time

2. you can hand tighten just the bottom foot on one side of the comp and tilt into place (good for getting the hard to set ones in the back)

3. With two people you can hand tighten all 4 feet and set the compressor in 1 step
