This is advertised to fit the xt, but it cannot be placed with grates aligning flush. Makes it pretty useless.

I bought this for my Gravity XT. It is a 1/3-grate griddle, not half. And it isn't a true insert because it is slightly wider than the grate it is replacing -- so they don't create a continuous flat surface. I have to sit it on top of the grate, which is less than optimal. It also scratches easily. I wish Masterbuilt would introduce an insert that is purpose designed to fit an XT -- either 1/3, 2/3, or full grate insert. At 1/3 size, it is actually too small for many purposes. I only own one, but I would think two side by side wouldn't work with the lip between the two.

If I wanted something that want a true half sized I could have bought aftermarket.

I bought 2 of these griddle inserts for my XT, They worked making chicken quesadillas, but I was cooking for just 2 of us and there just wasn't enough room. I would have liked to be able to get a griddle insert like the ones for the 1150 that is 1 full size piece instead of having to buy 2 that don't cover the whole space of the XT. it was to hard to work with because of the edges where the 2 came together. I would like to try fried rice on it, but I think it will be frustrating trying to do it on the 2 inserts. I think this could be improved with just 1 solid piece that covers the cooking area.
