SWISCO - The Replacement Hardware Authority

My nameless window parts

A home owner from Gastonia NC says:
I cannot find any identifying marks on any of the hardware, I had to cut the vinyl to remove these parts. The window sash weighs 15 pounds, is 32 inches wide and 26 inches high. I believe that boths springs run in the same track.

The pivot shoe resembles our 15-111. I also recommend two S160-7 coil springs for each side. I'm not sure how they lock the two springs together in your window, but with ours, you will lock one spring in the 15-111 shoe and lock the second spring into the hole of the first spring; think of it like a piggyback. Then you place the nylon cover over the springs and screw to the window frame.
