My favorite hopper window in the vinyl industry to install. We we remove the operable sash to set the frame. I've requested that the Q-lon weather-stripping be about 10-15% larger to contact better to the master frame as one cannot "cheat" or intentionally rack the frame over on something like 14"- 18" over very well like a double-hung. You can see the gray weather-stripping on the sash isn't touching the jambs, only the poly fiber is and one can see direct daylight through that stuff. OKNA says I'm crazy, but what do I know? I've only installed 50,000 vinyl windows in my career and the highest "Yoda" like level.................
Hello, you have to check and see if there is no child lock in your window. Sometimes these windows come with a child lock as a safety, so children don’t climb through the window
