I am finishing some pocket doors I installed in my basement as part of a basement finishing project. Is it customary to use door stops on the strike jamb or the top (split) jamb? Thank, Guy

Hello, I am in the process of measuring for new replacement windows and have run into a puzzling situation. Background info: I will be replacing 13 original double hung wooden windows from a house built in 1977. Windows appear to be standard sizing but here is the issue. - Window #1 appears to be a standard RO of 28X38 sized window. Measuring on outside brickmold I find exact measurements of 27¾ X 37 ¼. This would be good news as I see that this is a stock sized window. - My problem occurs when I measure from the inside. When I measure from both ‘interior stops’ I only measure 27 ½. Thinking I must be missing something I then removed the interior stops on both sides to get a better look and realized that the window tracks are recessed approx. another 1/4'” on each side and this is why my measurements aren’t adding up. So long story short: 1. Why won’t my measurements add up to the 27 ¾ even when the stops molding are removed? Was the trim originally installed incorrectly? 2. When ordering the new replacements it would be great to go with the original stock sizes but will I have to go with a slightly smaller measurement? Thanks for any input!
