A crank casement stay pin is a small but very important part of your window hardware. It helps keep the crank casement stay tight against the side of the window frame, preventing it from swinging open. These stay pins are very useful on older windows, as they’re very hard to find these days.

The From the Anvil Cranked Casement Stay Pin (Bottom) is a simple, classic design that works great for any window in your home. It’s made from high-quality cast iron and has been heat-treated for durability. This stay pin can be used on both single- and double-hung windows.
