Double hung window stops
A handy person from Chilton, Wisconsin says:

I need double hung window stops that insert into the top sash to stop the lower sash from opening more than a couple inches. They can retract in, so the window opens all the way up. Approximately 1/2 inch wide and 2 1/2 long, brown in color. Need 6. Thanks.

Could our 26-148 be a match for your current stop? If not, please remove it from the window and take a few pictures of it for us to see. Thanks!
