When officer Sara McClurg of the Clackamas County Sheriff’s Department spoke at the Neighborhood Watch meeting she said that due to the newness of our homes, our dead bolts should be up to standard. That is a one inch throw and three inch screws anchoring the strike plates. Both of ours had one inch throws, but the holes in the door frames were only drilled out to about one half inch. The strike plates were mounted with three quarter inch screws. The bottom line is that they were installed for looks – not security. If you’re concerned about security, I’d suggest checking the installation of yours.
