Product review (4 stars): using in Masterbuilt 30 in propane smoker
Fits perfectly in burner opening to hold cast iron pan (to hold smoke chips).  I did this to replace the smoke pan that came with the smoker.  Although the grate appears thin, it has gone through approx 20 smoke sessions running up to 12 hours and has held up.  At night, the grate is glowing red from the heat.  No warping or breaks yet.  Rust has started, but that is expected.
