Where can I find pivoting hinges for a pivot transom window? [closed]

Question

We are rebuilding some above-door wood center pivot transom windows, but I can't for the life of me find a hinge that will stay where the window is rotated to.

The window looks like this:

When open I would like them to stay at a 75-90 degree angle. I keep reading about pivoting friction hinges, but I can't find the right shape that will attach properly to both the casement and the sash.

I've tried the following: Friction Lid Stays (both curved and straight), chains, spring lid supports, lid hinges, magnets.

Got any ideas?

Thanks in advance.

Answer 1

You have center pivot transoms.

You cannot use pivot friction hinges in this application without doing a lot of work. To install these types of hinges you must remove the stops on both the sash and frame and rabbet out space to accommodate the hinge.

A cord attached to a block and tackle placed above the transom is your easiest solution. You may need to attach a weight on the top of the sash opposite the block and tackle to force the sash to tilt when you open it.
