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. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It is so nice to use the adjustable length deadbolt and have it ... *by R***R on Reviewed in the United States on July 9, 2018* Very solid lock and installed with ease. It is so nice to use the adjustable length deadbolt and have it work the first time.
