Help with window locks

[stalagmike]

I would like to fit a lock to this window (see pic) can anyone out there tell me the best way to do this? It looks to me like the previous owners of our house have removed some sort of lock and taken it with them. It's an aluminium frame. Short of replacing the handle for a lockable one, I can't seem to find a solution that uses the existing holes in the frame. Any ideas?

Do a search on lockable cockspur window handle, plenty on ebay, it's not expensive, check all the measurements of the holes dimension and the handle thickness etc

Also the strike plate wedges for cockspur handle

Any ideas on how to get the old handle off? Appears to be held on with rivets at the moment. Want to take it off so I can measure before buying new handles. Cheers!

I did the same thing for my old house, drill the rivets carefully. It may only be riveted as someone has already removed the screws which left too big a hole.

The cockspur locking handles have a variety of different depths which is the depth of the strike plate plus the depth of the plastic from the edge of the closing bit to the edge of the frame if that makes sense.

I think I get what you mean. This is the 'step height' that this refers to: -

As mentioned drill it out, the rivets ring is only soft metal

You can measure the handle while it's still on the windows
