    A quality Product!

Hi ordered a stainless steel single cylinder deadbolt and it is a quality product and easy to install.

    In my opinion these ARE NOT GRADE 1.  NOT A SECURITY LOCK.
  

*by K***K on Reviewed in the United States on October 11, 2018*

I questioned in my mind why a Grade 1 lock was so reasonable when I ordered four of them.When they came, I took one apart to check and make sure it was a Grade 1.  It turned out not to have the built in protections I would expect of a Grade 1.  In fact, I think it is very light weight and could be drilled out in a very short time and unlocked. It does have a hardened block around the tumblers but the screw holes are open to the front and would guide a drill, and tumblers appear to be unprotected in a brass block and easy to drill out. Amazon does have a secure lock at $155+$15 shipping with the Mul-t-lock Hercular Single Cylinder deadbolt.  They are also advertised for as much as $229 on Amazon.
