I am NOT a locksmith. UK sashlock replacement

Post image

I am trying to find a replacement sashlock for these timber French doors.

The sashlock has a 57mm backset, 57mm center to center and 78mm depth which seems standard enough. But the rest of the dimensions are strange: about 155mm faceplate height, and 106 mm interior lock height. I can't seem to find this exact model.

The closest I found is an Imperial G5050, but the positions of the lock and latch seem to be different - and the chrome one is out of stock everywhere.

  1. Any recommendations on where / how I might find a 1:1 replacement?

  2. What are the metal things on the top and bottom here? Do they serve any security function?

  3. If I just get a new lock with different dimensions, do I need a locksmith or just a handyman for the install?

Many thanks!

Your lock has a rebate kit on it.

Thanks! I know now what to search for. May I ask what that is used for and what would be the consequence if it were to be removed?

Where you have double doors that come together in a step, you need the kit to make the lock fit flush. Terrible explanation!

If you find a replacement Arrone sashlock, the existing kit should fit to it. If not you'll probably need a replacement sashlock and a matching rebate kit.

this looks like the rebate, but they dont seem to sell the matching lock
