フラットスクエアシングルシリンダー機械式デッドボルト

Swapped out my old worn lock for this one and the difference is night and day, the bolt slides smooth with zero wiggle. The square plate sits flush against the door and looks way more expensive than what I paid. Feels solid enough that I stopped worrying about the back door.

Installing this deadbolt was straightforward, and the solid metal construction gives it a reassuring weight. The smooth turn of the thumb latch feels precise and reliable.

The square faceplate sits flush against the door and looks way cleaner than the round one it replaced. Turning the bolt feels solid with no wiggle, and it locked smooth on the first try after I lined up the strike plate.
