This Is Why Some Window Grills Have a Curve at the Bottom

Ever notice those window bars with a little bulge, often called a “potbelly”? They’re more than just decorative—they serve some smart purposes. Let’s explore why these quirky window grills are both practical and stylish.

What Are Window Bars Used For?

Window bars, or security grills, have been around for centuries, mainly to keep intruders out while letting in light and air. They’re commonly made of metal and used in areas where extra security is needed, like ground-floor apartments.

Why the “Potbelly”?

That bulge at the bottom isn’t just for looks—it actually adds strength and versatility. Here’s why:

  1. Enhanced Security: The curve makes it harder for intruders to grip and manipulate the bars, boosting security.
  2. Flower Boxes: In some places, the bulge creates space for potted plants or flower boxes without compromising safety.
  3. Child & Pet Safety: The curve provides extra space, making it safer for families by preventing falls.
  4. Aesthetic Appeal: The curved design adds elegance and can complement the building’s style, especially in historic areas.
  5. Easier Cleaning: The extra space makes it easier to clean the window glass.
