Steel window sash clips for metal-sash glazing
You can’t drive a glazing point into a steel or aluminum window the way you can into wood. Sash clips are how you hold the glass in metal sash while you putty. These are 18-gauge steel spring clips, the ones professional restorers reach for on metal windows.
They snap in and hold the glass tight against the frame so it can’t shift while the putty sets. Once the putty cures, the bed does the holding and the clips stay buried underneath.
The details
- Material: 18-gauge steel
- Type: spring clips
- For: steel and aluminum windows

- Sold in 50-packs and 1000-packs
