NuSet Kwikset Keyed Double Cylinder Deadbolt (Satin Chrome)
A double cylinder deadbolt is typically used on a front or back exterior door and is operated with a key from both the exterior and interior of the home. It is recommended when a window is in close proximity to the door. The interior keyway prevents an intruder from accessing your home by breaking the glass and turning the thumb turn to open the door. Polishing brass finishing is also available.
