Saw the reviews on potential issues with older models. Bough mine in 2014 (I think). Had to break out the metal file to grind down a few burrs/welds and rubber mallet to seat it but worked find and VERY nice to have pot a little higher. Didn’t realize just how much it would help. If you buy wit a new burner I expect it will slide in with no issues.

Excellent, efficient, heats water fast, uses less propane.

Very strong and well made highly recommend these

The extensions I received did not include instructions, so it took some time to figure out assembly. The extensions have a metal insert that connects them to the burner (the insert is only screwed to the extension and can be separated). However, the metal sleeve on the burner is slightly indented, so I had to tap the metal insert into place with a hammer to align the screwholes between the insert and sleeve. If you tap the insert in too far, you are hosed - I don't know how you could pull the insert back without scratching the burner itself. So, be gentle with the hammer tapping! Once the metal inserts are in place and screwed in, attaching the extensions and cross-bracing was straight forward.

I agree with others that the burner is quite sturdy with the extensions and raises the kettle to a comfortable height.

At first I was reluctant to order these extensions due to the one star review posted in back in 2017. But I went ahead and ordered them anyway. My burner was purchased back in 2014 and the extensions fit fine. So if your Edelmetall burner has 1” O.D. (Outer Diameter) square legs this set will fit just fine. Nice and sturdy and well worth the purchase.
