Term for this Window Hardware

chrisincr | Posted in General Questions on

Can anyone tell me what the mechanism on this old window is called? It a basement window obviously, but I can’t quite determine the name of the hinging/removal mechanism.

    Can't quite tell what I'm looking at in the photo, but
    a. this looks to be a steel frame window. They have different mechanisms than wood windows
    b. looks to be a "awning" type mechanism/operator. Fairly common in old steel windows. Might also be a casement type mechanism

    I think they are called “hopper style basement windows”

    My guess is that style window was made by several manufactures over several decades. I think they were more or less generic and the lowest cost item tended to be the most popular.

    If you are looking for replacement parts I do not think you are likely to get any new replacement parts as the manufactures are likely long out of business.

    The parts are pretty simple and could be fabricated locally if necessary.

    Basement windows are so rarely operated most people would glue them closed caulking.

    I rarely recommend window replacement but steel and aluminum framed windows are my exceptions. If you heat and cool the basement and plan on staying a while replacement may be a smart move.

      Thanks Walta! I like being able to take the window out altogether to feed materials into the basement. I'll probably replace 3 of the 4 until I can get a set of stairs down into my basement!

    In case you're interested, here is a video where a homeowner is replacing a rusted-out hopper window:
