Unlacquered brass safety rosette, round

The comprehensive unlacquered brass security rosette collection includes all anti-pry rosettes for front doors in solid brass without a UV-protective lacquer coating. For authentic 1930s home restoration where natural patina evolution is desired with a complete brass package. What is a security rosette: a rosette surrounding the profile cylinder that offers active anti-pry protection. A hardened steel core or free-rotating collar prevents cylinder prying with a claw puller. Mandatory for SKG3-compliant villa-grade security hardware (5 min resistance). Versus titanium PVD version: the brass titanium PVD security rosette remains stable for 15+ years without patina; the unlacquered version evolves. Unlacquered character: develops patina from bright gold to warm brown in 1-3 years on a UV-exposed front door (faster than indoors). In this collection: 4 Intersteel versions. For the specific round version, see unlacquered brass safety rosette Round (subcategory, identical products).
