Aluminum Shabbat Blechs are customarily used on Shabbos and placed between the stovetop and food, so that the food stays warm throughout Shabbos.
The L Shape Blech has an extra section that points down to cover the knobs so that there is no accidental moving during Shabbos.
- Flat Blech: This is the most common blech style, it does not have any oven knob covers.
- Current product: L Shape Blech: These are flat and thin but have a lip to cover the oven knobs. These are ideal for families with young children who might tinker with a lit stovetop.
- Water Blech The water blech has a hollow center where water can be placed, this is ideal for higher heat levels. But make sure the water doesn't boil out!
