Round tumbled brass safety rosette. SKG3 cylinder rosette with a round shape in a matte gold finish

A round tumbled brass security rosette is a round cylinder rosette for the front door cylinder hole that covers the cylinder and simultaneously serves as core pull protection. A recessed steel rosette that prevents a burglar from forcibly pulling the cylinder core out of the lock. The round shape matches front door hardware with round elements (such as Hardbrass front door sets with round fittings or classic villas with rounded front door elements). The tumbled brass finish. Mechanically processed by rotary tumbling with ceramic grinding stones until all corners are rounded. Provides a subtle matte gold tone without factory shine.

At Deurbeslag Expert, you will find 3 tumbled brass round security escutcheons from Intersteel in SKG3 version: models with core pull protection (recessed steel ring to prevent cylinder extraction) and 1 model without core pull protection (escutcheon only). All are solid brass with a tumbled finish, fixed M5 screw fixing for mounting on an SKG3 cylinder lock, suitable for front door thicknesses of 38-65 mm.

What does the core pull protection do?

Core pulling protection consists of a solid steel ring around the cylinder core, firmly recessed into the rosette. During an attempted burglary, the burglar tries to gain a grip on the cylinder core with a screw or claw wrench to pull it out of the lock (core pulling attack. Responsible for approximately 60% of successful cylinder burglaries). The hardened steel core pulling ring blocks this grip; in combination with an SKG3 cylinder lock, this is the standard protection for residential front doors according to the Police Quality Mark for Safe Living.

Round vs. square. Shape choice

The choice of shape is purely aesthetic and depends on the overall style of the front door hardware:

Round rosette (this assortment). Matches round/oval front door hardware, Hardbrass Rond sets, classic villa with rounded elements.
Square/rectangular rosette. Matches square or rectangular front door hardware, modern style.

The safety function is identical in both versions. Only the visual connection to other fittings differs.

How do you measure a security rosette

Three dimensions determine the fit: PC dimension of the cylinder hole (typically 55, 72, or 92 mm. Measure the distance between the handle hole and the cylinder), cylinder through-hole diameter (Euro profile 17 mm standard), and door thickness (38-65 mm for a front door). The rosette is screwed through the door into the SKG cylinder; M5 screws and mounting instructions are included. If you have any doubts about compatibility with an existing cylinder lock, please send a photo of the lock and door to info@deurbeslag-expert.nl.

Maintenance

Wipe monthly with a damp microfiber cloth and mild soap. Do not use scouring pads, ammonia, acetone, or brass polish on the tumbled finish. Once a year, apply a puff of graphite lock lubricant to the keyhole of the cylinder mechanism (no oil or WD-40). If the lock is stiff, try lubricating spray first before replacing the cylinder.
