21 x 16 Inch Glass Top
The heated surface measures 21 by 16 inches, which takes two 13 by 9 casserole dishes side by side, or a couple of 9 by 13 pans plus a couple of smaller dishes. One owner fitted five dishes for a party, and another held two catering lasagna pans for a Christmas dinner. The top is black tempered glass framed in stainless steel, a hard, flat surface that looks smart on a buffet and wipes clean in seconds, and it does not wear or stain the way a soft mat can. The trade-off is grip. The glass is slippery and has no raised edge, so a hot pan can slide as you scoop from it, and anything soft placed underneath to stop that would also block the heat. Holding the dish steady with a folded cloth while serving, or using pans with handles, is the workaround. Unlike a roll-up mat, the tray needs a flat storage slot a little larger than its 21 by 16 inch top.
