    Great Product & Sales Service

    Posted by Roger Palmer on Oct 13, 2020

    I ordered 3 each of the Schlage orbit keyed entries with matching B60 Deadbolts, all with satin nickel finishes. I also took advantage of standard offer to key everything alike which is one of the reasons I went with "Door Locks Direct". These locks were for my home and it has been several years since I have needed a change in locks. I was pleased to see that Schlage quality has not declined like so many other brand names products have. The first class manufacturing quality and finish are still very apparent.

    I also chose the Schlage dead bolt because I wanted the "Grade 1" security rating which is the highest rating for residential locks. "Door Locks Direct" prices were excellent, shipping was fast and they were quick to call me directly when I introduced some confusion via the notes in my order. I order online a lot thru a major well known retailer we all know. However their selection, prices, customization options, and customer service did not measure up for this purchase.
