Basic 1” white vinyl window blinds with pull cord and rod. Plastic brackets included. Working fine, just upgraded to matching 2” blinds in my office windows.
Were previously installed in a 46” opening. I think there was a little bit of lateral play in the brackets when installed so you might be able to get these into a slightly smaller window.
Not 100% sure of the height, they were installed in a window that’s 33” high so maybe 36” or possibly longer, like 42”?
