Here’s What Those Window Bars With a Potbelly Are Actually For

Have you ever walked down the street and noticed quirky metal bars sticking out just below the windows? Those are window belly bars, also known as potbelly grilles. While they might look purely decorative, they’ve been used for practical purposes too.

What are Window Belly Bars

They’re a unique architectural feature, usually made of metal. They curve out from the window, creating a “potbelly” shape. Their primary purpose is extra security. They’re often seen in older buildings with a bit of vintage charm, adding to the overall character of the structure.

Where Are They Most Common?

You’ll typically spot window belly bars in older, historic buildings. Cities with a lot of Victorian, Georgian, or Art Deco architecture—like New York, London, or Paris—are prime locations for these charming bars. They add some character to buildings, whether it’s an old apartment building, a townhouse, or even a commercial property.

Are They Hard to Install?

If you’re considering adding window belly bars to your space, they’re not too difficult to install. Most kits come with pre-cut bars and brackets, so it’s mostly about measuring your windows and attaching them securely.

However, if you’re dealing with an older building, hiring a professional is a good idea to ensure the bars fit correctly and don’t damage the structure. Especially in historic buildings, you want to ensure the installation doesn’t interfere with the overall integrity or aesthetic of the space or go against any city codes or HOA rules.

Make sure the window frame or surrounding structure can handle the weight of the bars, and you’ll have a fun, charming addition to your home.
