Alenco Lock

Thanks for posting. Take a look at our 38-095, 38-096, the 38-138 or the 38-139. See if one of these four items is a match for your old lock. Compare the dimensions listed on each product page, especially the distance between the lip of the housing (be sure not to start from the 'outer' bottom of the base!) to the end of the prongs. For example, in the picture below of the 38-096, this dimension is 1-7/8". See which item corresponds closest with your old part.
