Cylinders & Cores

When it comes to commercial door hardware, people often assume the term cylinder and core refer to the same thing– but they don’t. The term cylinder refers to the entire locking assembly, while the core is the part where you insert the key to operate the locking mechanism. Understanding the difference is essential in identifying your commercial hardware needs. 

At Quality Door and Hardware, we carry four types of cylinders; key-in cylinders, mortise cylinders, rim cylinders, and thumb-turn cylinders. We also have different interchangeable cores as well as different tools and accessories to make installation and repair easier. With our impressive catalog from reliable brands like Sargent, Yale, and Schlage, we are sure to be your one-stop shop for any commercial cylinder and core needs.
