The glazing in my alenco window looks like 55-161-3 except the small leg on my glazing is 3/16 not 3/8. I am thinking I may have the 55-174 but there is not a dimension for the short leg shown. any chance its 3/16.

Thanks in advance for your reply.

Thanks for posting. Could we see a picture of your old glazing's end profile? And could you confirm all dimensions for us? That should help us identify a possible replacement. Thanks.
