The Cosmas 300 Series Oil Rubbed Bronze Handleset with 50 Series Interior Lever combines a classic exterior handleset design with the ergonomic comfort of the Cosmas 50 Series interior lever and a matching single cylinder deadbolt. The 50 Series lever features a smooth ergonomic curve with a fuller, traditional profile, delivering both comfort and timeless appeal for your front entry.
The rich oil rubbed bronze finish showcases deep brown tones with subtle copper highlights, pairing beautifully with wood doors, rustic fixtures, and classic architectural styles.
The included single cylinder deadbolt uses a Kwikset KW1 5-pin keyway, locking from the exterior with a key and from the interior with a thumbturn—ideal for secure residential front and side doors.
Tip: Select Keyed Alike when ordering multiple locks so all keyed items use the same key.
