Go beyond basic security with the Arrow E Series Deadbolt, a heavy-duty deadbolt that meets Grade 2 standards. A spinning collar, a hardened steel pin insert within the steel deadbolt and hidden mounting screws make this deadbolt highly resistant to tampering and damage for added piece of mind. Available in three sleek finishes, the residential deadbolt has a classic design and fits 1-3/8-inch to 1-3/4-inch doors.
