The house I bought has an older greenhouse attached that needs some repair. I’ve been looking all over online for parts but have not been able to find any matches. I’m hoping someone here might be able to help me identify this glass panel clip. The tabs on either side of the screw drop into a channel on the supporting frame and expands when the screw is tightened to hold the clip in place. One set of feet on the spring clip rests on the metal of the bar cap and the other on the glass panel above. I hope I’m using the terminology correctly. The “bar cap” is shaped like a lower case h with the lower glass pane sliding into the bottom channel and the upper pane resting on the upright.
