Beags,
Having purchased the aforementioned 'Hinged Grate' to replace the tired and slightly rusty one piece grate on the trusty One Touch Bar-B-Kettle, and having used it for the first time today, I can only sing its praises. I does actually do exactly as it advertises and allowed me to refuel twice, whilst still cooking. An ebay bargain at only £18.99
