I need to replace a tubular latch. Length of case either 116mm or 4.5 inches. Have looked everywhere but it seems this size is not available. The one I’m replacing is marked E*S SUPA. Anyone know where to find one?
 
Got a picture?
Not a size I've seen. Is it old?

The backset is more important than the case length. What is it?

This one has a 128mm case and a 107mm backset. It's a very good brand. It replaces a 5-inch case and they also do a 4-inch

I might have some horizontal latches and sashlocks somewhere, but the case is bigger so you'd need a chisel.

You might find an old stock Legge on ebay but it will probably be 4-inch

So 100mm backset, or 4 inches is near enough.

(You measure from the edge of the door, or the front of the fore end plate, not behind it)
