Unlike most other trivets, this clever design can be expanded to  accommodate extra-large pans and oven trays or even multiple serving  dishes. Made from durable 18/8 stainless steel, it features non-slip,  non-scratch feet that are suitable for all surfaces and is heat-resistant up to 340˚C (640˚F). Perfect for protecting surfaces from scratches and heat damage. Conveniently folds for compact storage.
