Antique black Urn door knocker (197mm x 114mm). Suites with Kirkpatrick door handles and letterplate. May not be suitable on some smaller doors due to size. The Kirkpatrick name has been synonymous with the production of high quality malleable iron ironmongery for 150 years. The traditional style and design of this range will greatly enhance the look and feel of your timber door. However, by nature, these traditional products will not provide the levels of performance of their more modern counterparts. The Kirkpatrick black antique door knocker, as with iron in any form, is susceptible to rust.
