Why You Need a Lock Cover

• Weather protection — keeps rain, snow, and moisture from corroding internal mechanisms
• Prevents jamming — blocks dirt and debris that can cause keys to stick or fail
• Tamper resistance — visual deterrent against vandalism and lock picking
• Extends lock lifespan — protected locks last significantly longer in outdoor mailbox installations
• Easy installation — slides onto the existing K91910 in seconds, no tools required
