The best deadbolt locks to prevent home invasion are those with Grade 1 rating. These deadbolts have a one-inch throw bolt that extends deeply into the door frame, providing excellent protection.
'Install a Grade 1 deadbolt lock with a one-inch throw bolt. Ensure it has a reinforced strike plate and long screws to secure it deep into the door frame,' says Chris Purvis, owner of CCA Concrete Contractors. Ensure that the deadbolt strike plate is secured with long screws.
