Frame & Hardware Are As Important As The Door

Most people focus on the door itself. The real vulnerability is usually the frame or the hardware around it. A security door is only as strong as what it's mounted into – and that's exactly where we put our attention on every job.

What Makes a Commercial Security Door Secure in NYC?

Not all security doors are the same. And in a city like New York, the difference matters. 

The security rating of a door is determined by its core material, frame construction, locking mechanism, and installation quality. A correctly-rated door installed poorly is still a vulnerability. 

That's why specification and certified installation are inseparable when it comes to commercial security.
