Broken holding tank handle

Hi Jim, You really should go in from underneath. Trying to cut through for overhead is risky, from the side is not advised as this goes through the I beam which should not have an enlarged hole as it reduces structural integrity. I have pulled a series of screws from the wrap around aluminum and found it was enough to gain access to this area. My case I was running 6awg wiring to some switches mid-coach. Maybe others have better ideas....
