I am looking for replacements. The cardboard "T" was cutoff to try some rollers I bought. It needs to be there. The roller material is steel, diameter 1.25, width 5/16, roller housing height 1", roller edge concave, housing width 3/4", overall width 7/8", roller housing length 2-1/4".

Take a look at our 81-162 roller, this looks like it could be a good match. let me know what you think.
