Depth dimension of your & 89-021D

Is the depth dimension of your 89-021 the same as the steel version, 89-021D, which is 7/16" ?

The reason I'm asking is I need to replace a Weathershield sliding glass door "Recessed Lock Raised Jam Keeper" part # 972496 (This is not the actual part number off the piece, it's a number I got from the Weathershield website parts listing). My part looks pretty much identical to your 89-021D, has the same dimensions of 4 1/4" x 5/8" x 7/16", and it's most likely diecast aluminum or pot metal. I would like to replace it with the steel version, so hopefully the 89-021 depth dimension is the same.

Thanks for the help.
