Kwikset's new Dorian lever in a competitively priced lockset that complements the company's popular line of interior levers.
The lever is "non-handed," which allows it to fit on both left and right handed doors.
"Consumers are more often choosing levers for both interior and exterior doors," said Mark Burchfield, group marketing manager for Kwikset. "Levers are seen as more stylish."
The levers feature a patented ergonomic design with maximum hand grip area. Both the dummy functions and passage functions meet the requirements of the Americans with Disabilities Act (ADA). The levers are available in five finishes that carry a five-year warranty. The levers are covered by a 25-year warranty.
