  • One sided Deadbolt
    5

    Posted by WillysGuy on Oct 28, 2026

    I bought the Schlage B80 one sided deadbolt for additional security on the secondary door from my garage in to the house. The handset there was a simple push button lock and I felt that I needed something more formidable and the deadbolt was a much more economical solution then a new keyed handset. The best thing about it is there is no indication there is a deadbolt on the garage side, its all on only one side of the door. Also, its a much more aesthetic look then a utility bolt and matches the handset. Door Locks Direct, of course, was awesome. They are my go-to supplier for Schlage door locks having supplied all of the keyed alike handsets and bolts for my previous homes. Fast shipping and extra care with all of my orders, even calling me personally when I have no provided sufficient detail. Five star product and five star service.
