Looking foran Andersen tandem sash (LH) that is 41" long point to point. The part # on the keeper says it is 135143 but your equal part online shows it at 29 1/2". I also included a photo that ahows 7=LH, 8=RH?
Please help!

This looks similar to our 38-146 Andersen brand single lock. Could this be what you're looking for? It's compatible with the 39-291 lock handle.

Im looking for the Andersen tandem lock for a casement window. It measures 41" from tip to tip and the glass daylight opening is 55". The one on your website shows it to be 40" and it is a LH.

I took one of the 38-149 long locks out of stock to check the numbers marked on it and they match up to yours. #135143 and the #7=LH and #8=RH. Take a look at the 38-149 and compare the dimensions with yours. I think this may be just what you wanted.
