The Delamain DK39C Ringed (Concealed Fix) Door Knob on Rose Polished Chrome has a simple classic look about it that makes it suitable for all types of interior. It can look just as good in a modern property as in a more traditional or period home. The door knob has concealed fix roses and screws are supplied.

The finish of a door knob really does change the character of it quite dramatically, as the Delamain plain door knob in polished chrome shows, as it can look stunning in a more modern property simply because of its shiny silver colour.

Matching Accessories for the DK39C Door Knob

Please note – when purchasing locks and latches to us with this knob we recommend that they have backsets no smaller than 82mm (with a 102mm case) to accommodate the size of the door knob. Larger sizes can be used to allow clearance of decorative edging on the door. 

An appropriate heavy duty latch like the Carlisle Brass Delamain mortice latch will be required for all non-locking internal doors.  These are available separately; see Related Products and the Hinges, Locks & Latches category. 

Matching key escutcheons are available for doors you may wish to lock.  An escutcheon is simply a cover for the keyhole cut-out in the door.  Usually one pair is required for each door, ‘standard’ for doors with sash locks and ‘euro’ for doors with cylinder locks.  Locks are available separately; see the Hinges, Locks & Latches category.

Matching bathroom turn and release sets can be fitted to bathroom doors which will allow the door to be locked with a small turn knob in the inside and opened via a coin slot on the outside in the event of an emergency.  Using a turn and release set is a requirement of Building Regulations for new-build projects and is a very safe and convenient way of locking a bathroom door for improvements to existing buildings.  A matching bathroom turn and release can be found in the Related Products. A bathroom deadbolt or a bathroom lock would be required and these are available separately; see the Hinges, Locks & Latches category.
