Looking at 38-174 but have a question
We do carry another lock similar to the 38-155, but the base to the top of the handle is also over 1". I wonder if it could be that you have an older style. I recommend checking to see if the base where it locks is the same as yours.
We would also be happy to take a look at the hardware in question if you can upload some photos along with the measurements.
The 38-174 handle could be taller to get a better grip on it. I would think the base and the lip on the locking part height are what would be the important measurements. Can you write out the height measurements of the base and lip?
Between the two handles, the 38-174 does seem to be the handle you need for your window.
