The Dexter by Schlage Corona Knob Bed and Bath Lock in Satin Stainless Steel is perfect for use on doors where locking is needed. Inspired by designs of the 1950s, the Corona knob’s strong spherical shape adds a geometric touch that works well in contemporary settings and becomes especially edgy when finished in Satin Stainless Steel. Plus, it’s been designed and tested with strength and durability in mind.
