Some window grills have a curved design at the bottom for a specific reason.

One important use of potbelly bars is for “putting flower boxes.” The rounded part gives a steady base for homeowners to “add some plants and beauty” to their windows. This design improves how a building looks and keeps it safe.


Moreover, potbelly bars can be helpful for installing air conditioning units. The additional room they offer guarantees “good airflow and cooling” without sacrificing anything.
