A round security rosette (synonym: round cylinder security rosette, round anti-pry rosette) is a round rosette surrounding the profile cylinder of a front door. It offers active anti-pry protection for SKG-compliant security hardware. Difference from a standard cylinder plate: A standard cylinder plate (see cylinder plates) is merely a decorative cover plate without an anti-pry function. The security has a hardened steel core or a free-rotating collar that prevents the cylinder from being pried out. A burglar cannot pull the cylinder out of the lock with a claw puller or special tools. A mandatory component for SKG-compliant front door hardware (SKG2/SKG3). Brass titanium PVD version: titanium nitride PVD coating on a brass base. 4500 HV hardness (5-10× stronger than electroplated brass), 15+ years UV resistant without fading. Premium version for villa-grade front doors. Versus square/rectangular: round is more common and visually matches round door handle rosettes and modern designs. In the Round brass titanium PVD security rosette collection, you will find 2 Intersteel versions with SKG3 certification and core pull protection.

What is a security rosette and how does it work?

A security rosette is an active security element at the cylinder passage in a front door. Problem without a security rosette: with a standard cylinder passage featuring only a decorative cylinder plate, a burglar can pull the cylinder out of the lock using a claw puller, crowbar, or special core-pulling tool. Once the cylinder is removed, the burglar can immediately operate the lock. Burglary is possible in 30-60 seconds. Security rosette solution: a hardened steel core or free-rotating collar surrounds the cylinder. In the event of an attempted force on the cylinder: The hardened core distributes the force over a large surface area. The cylinder cannot be pulled out. The free-rotating collar rotates along with the tool upon contact; the tool cannot get a grip. The cylinder remains firmly in the lock. SKG3 certification required: for SKG3 compliance (villa-grade security hardware, 5 min burglary resistance), a hardened security rosette with core-pulling protection is required. Core pulling protection: specific anti-pry design that protects the cylinder against core pulling attacks (most common burglar method for SKG2/SKG3 cylinders).

Intersteel round safety rosette versions

The 2 products are Intersteel security escutcheons. Dutch mid-segment, factory in Poland. Material: hardened steel core in a brass casing, with PVD coating in a brass tone. Hardness: 4500 HV. Impermeable with common burglar tools (crowbar, claw puller, core puller). PVD UV resistance: 15+ years without fading in normal outdoor use. Shape: round, standard Ø50-55 mm. For matching with round door handle escutcheons on the front door (visually coherent). SKG compliant: SKG3 certification. Meets villa-grade security requirements. Fixing: through-bolts M5-M6 through the door thickness to the inner security shield. Anti-pry requirement is enforced via the through-bolt fixing requirement of the SKG standard.

When do you choose this round version?

The choice of shape (round or square) depends on the other door hardware. Choose round: for a round door handle rosette or knob design on the front door (visually coherent); for a classic modern design where round elements are common; for typical Dutch renovations. Choose square or rectangular: for a modern, sleek design with a square door handle rosette; for minimalist design. Versus general security rosette category: Brass titanium PVD security rosette (umbrella, 2 versions). The round sub-category here is matching with round elements. Quantity required: typically 2; one on the outside of the front door (critical for anti-pry), one on the inside (typically a standard cylinder plate suffices on the inside, but for SKG3 a hardened version is often required).

Sizes and installation

Three dimensions determine installation. Rosette diameter: Ø50-55 mm, standard for Intersteel versions. When replacing, measure the existing rosette diameter. Cylinder passage: 17 mm for profile cylinder (Dutch standard). Fastening: M5-M6 through-bolts through the door thickness (40-65 mm front door) to the internal security escutcheon. Through-bolt fastening is mandatory for SKG certification. Installation steps: 1. Remove the existing cylinder plate. 2. Place the new security rosette on the outside over the cylinder passage. 3. On the inside, place the matching plate or internal security escutcheon connected with through-bolts. 4. Tighten firmly. There should be no play between the rosette and the door surface. 5. Test cylinder operation: insert the key and turn. The lock must operate smoothly; the security rosette should not rotate (free-rotating collar version) or should be firmly in place (hardened core version). PVD maintenance: a damp cloth is sufficient; do not polish.
