Storefront Security Gate Solutions In Chicago

Dynamic Closures is the proud inventor of the first side folding security grille. This breakthrough led to the founding of our company in 1975.

Since that time, our operation has grown tremendously, as we are called on to create storefront security shutters & doors, as well as other types of secure closures, for a variety of applications, including retail, community, and sports facilities. We provide products to businesses throughout the Chicago area, across the United States, and around the world.


The success of Dynamic Closures can be attributed to our three underlying core values. We spearhead innovation and improvement in our field, provide a top-tier product, and serve our customers devotedly.

Early in the 21st century, we updated our values with two equally essential goals for the modern world –1) a focus on environmental friendliness and 2) enhanced security for trade chains and international borders.

We put these goals into action in our business every day. First, for the past 15 years we have been working hard to green our materials and manufacturing processes, with the help of professional environmental consultants. Second, we have earned certification as a trusted trader by Partners in Protection (PIP) and Customs – Trade Partnership Against Terrorism (C-TPAT).

EZ Series doors are equally easy on your project budget, due to their affordable price and minimal installation cost.

At the same time, these strong doors provide a discreet, seamless look because their 6-inch pocket will fit in flush with your building’s commercial wall studs.
