I do not see that this is the replacement for the 52110. However, this 521121 was made for Suburban slide in cooktops. Below are the dimensions for this grate. If the dimensions seem to match up to what you need, you should not have any issues using this grate. Dimensions: 15.803” L x 19.418” W x 1.859” H.
