Our FR10 housing quote apparently carries the fingers for free

Both tooling suppliers cite the cast housing's mass, yet the proposed fingers project well beyond the wrist and neither load summary mentions the adapter. I have asked for the complete held assembly and its assessment, not a bigger reassurance in the same empty space. The cheaper quote may still be the better proposal. I just cannot tell while one side of the calculation contains the housing and the other side contains optimism. What information should our reviewer require before we choose between the two actual tool designs?
