Exactly as Advertised

Materials and specifications are correct. Timely delivered. Far less costly than same/similar product from other "antique hardware" sites.

Fantastic Replacement

Purchased several sets to replace the mortice locks in our bedroom doors. The originals throughout the house will need complete refurbishing, so I decided to replace the ones we encounter everyday. The action is smooth and quiet, finish is very nice, and they are surprisingly heavy duty compared to the locks I dug out of our 85 year old doors. The sizing was almost an exact fit, only needing <1/8th inch of chiseling in a few places. All in all we are very pleased with these locks, and the face plates and knobs we purchased were equally impressive. I will be replacing the locking mechanisms in our kitchen doors with these as well. Final thought: Hardwick and Sons has the best price for this set. I'm coming back here for a lot more pieces to refurbish other parts of our house!

  • A traditional & classic interior mortise lock set for doors. This lock is a replica of common-style mortise locks from the past century, although it will easily fit in with any time period in a home from early 20th century to current modern styles. The plates, latch & throw-bolt are made of high quality solid brass for a real handsome look. The thumbturn mortise lockset case is made of thick steel with a well-built internal mechanism & bolt, unlike many basic locks out on the market today. The 2-1/2" backset measures from the edge (front) of the plate, to the center of the hole. Beautify & secure your doors with this handsome & classic piece of hardware. For an emergency release key for the outside,  see here.

         Hardwick & Sons is pleased to offer vintage-style hardware for the many people who desire to fashion their homes with charm, quality, & style. The traditional-style hardware that we showcase are true & faithful reproductions of classic hardware pieces found in the many homes from across America throughout the past century.
