No but it could be used on those single burner stoves for the short black kettle.
Big Fella and myself decided what was available on ebay and most camping shops
for use as a trivet was shite , basically cake airing racks. I brought a Lodge cast iron
one from the states modified it and gave it to the Big Fella as he had a mate with an
iron foundry, He had his 7 in one kitchen tool made but don't know whats happened with the
trivet. I'm hoping to have a quality product at a competitive price, so others will see we'll not
stand for rubbish products at inflated prices. I think that happened with the inter cooler prices
To answer your question you would place the trivet in the base of your camp oven then put your
Roast on top in a foil tub. We use this system all the time with great success. Keeps your camp oven clean too
