*CNC'd parts are milled on a computer controlled lathe from solid brass bar stock. The pieces have literally been sculpted from solid metal, meaning there is no chance for pits or other defects often found in cast or poured products. They are the highest quality solid brass products you can buy, with impeccable detail and superior finish.

Turn any of our traditional spindle mount door knobs into a modern 2 ⅛" bore set with this fantastic “Volcano” rose kit!

Crown City Hardware exclusive, Signature Series, 2 ⅛” bore, Volcano rose conversion kit.

We know many of you share our fondness for traditional hardware. Unfortunately, while you love the door knobs on our site, which all utilize the classic spindle method of attachment, you're saddled with modern, pre-bored, 2 ⅛” holes. While there have been options and adaptors for dealing with this, they've usually been unattractive and cheap...until now!

We are very proud to introduce our custom designed 2 ⅛” adaptor kit, utilizing our exclusive, Signature Series CNC'd* “Volcano” rose. The rose is an absolute marvel! It's beautiful, featuring a simple, traditional design that pairs elegantly with most of the door knobs on our web store. It has an ingenious, completely screw-less design. It’s incredibly easy to assemble, as the rose simply threads on to our high quality, solid brass 2 ⅛” bore adaptor.

Once threaded onto the adaptor, the pair form an incredibly solid, stable mount that feels as if your door was never bored in the first place. It feels as if there is still solid wood underneath the rose, leaving your door looking, and feeling, as if it has classic spindle mount hardware.
