Hy Stoveboltkid, I'm going to assume you want to compare frame sizes. You didn't specify which model, so I'm going to use the 4108 and 4408 for comparison.
4108 frame dimensions 7" X 2 3/4" X 7/32" section modulus 5.52
4408 frame dimensions 8 7/8" X 2 7/8" X 1/4" section modulus
8.80
so to answer the question the frame on the 4400 series is larger in every dimension, hope that helps.
