Tips & Tricks

We've been told to look for a Grade 1 deadbolt installation — what does that rating actually mean for our home's security?

ANSI Grade 1 is the highest residential and commercial deadbolt classification, meaning the lock has passed rigorous cycle, strength, and security testing — it's the standard we recommend for exterior doors on Columbus homes. Installation done correctly ensures the full bolt throw seats properly into the strike plate, which is where most deadbolt failures actually occur. Call Sundial Locksmith at (480) 525-7778 to have Grade 1 hardware installed the right way.
