Security grades

While the styles we offer have changed to reflect the times, Schlage has upheld the same commitment to quality for decades. That’s why our door hardware is volunteered for testing against the highest industry standards, like the new BHMA residential grading system.

BHMA is a group of industry experts who grade residential door hardware performance in the categories of Security, Durability and Finish. A grade of ‘C’ is good, ‘B’ is better, and ‘A’ is best. A grade of AAA is the best grade possible in all three categories.

Schlage offers products that range from AAA to CCC, so that any homeowner can find the right fit for their needs. In addition to these high industry standards, we test our products even more rigorously in our own labs. By raising the bar even higher, Schlage offers products that stand up to the trials of life for years to come.

The new BHMA grading system lets you decide whether Security, Durability or Finish is most important to you, so you can then choose the product that gets the highest grade in that category. For example:

  • If your children arrive home from school first and you want to ensure their safety while you’re away, you’ll want to invest in a lock with a Grade A in Security.
  • If you live in a busy household with constant coming and going, you may prefer a lock with a Grade A in Durability.
  • Those with homes exposed to changing seasons may look for a lock with a Grade A in Finish, so they feel confident that their new lock’s finish will hold up against the elements


A measure of safety. Measures the hardware's ability to withstand:

  • sledgehammer attacks
  • attempts to manually pull it from the door
  • weight, like a child hanging from a door lever
