    A really good replacement for our old locking mechanisms from the 1980's, (not available now ). It fitted easily. Even though it was slightly longer than the original . The window now shuts smoothly and positively. Thank you.

    Good quality item used as a replacement for an Imperial Hardware unit that I couldn't find a supplier for. Direct swap and didn't even have to move the keeps... (more by luck than judgement.) Looks better quality than the original as well. Usual quick delivery by Handles and Hinges.

    the parts were entirely adequate for the job, but the service the team provided is what deserves the highest praise. They could not have been more helpful. I am indebted. I did not know how I was going to fix my problem, but H&H sorted it. Many thanks.
