Pêne dormant rond à cylindre simple avec tournevis ovale

The lockset appears to be very high quality. Seems to be worth the price, expensive but you get what you pay for.

I looked at many websites and across multiple brands for a door handle that is 305 or 316 Stainless steel will hold up to salt air corrosion for a beach house. Linnea is the only brand at a reasonable price I found. In also worked with Kent at Linnea to help consolidate my order. He was wonderful! I have not installed but am very happy I found this product on Wayfair.
