Spacer blanks are an essential part of a professional and efficient rack build. Use them in your rack design to conceal any empty spaces in your rack, giving that professional touch. Installing spacer blanks also bring other significant benefits apart from making your rack look good.
Once installed they will also control the airflow within your rack; this is especially important if you are building out racks in a hot/cold aisle configuration. Additionally installing spacer blanks will also add strength and rigidity to the rack they are mounted in.
