Double end bag installation

I bought a double end bag but i didnt like the cables that came with it, so i bought two Title's wrapped rubber cable that cames with hooks in the end of it. Should i put the hook directly on the double end bag? In the floor im using a Everlast anchor that you fill with sand and cames with a chain. I want to know how should i adjust the height with this cords and what should i do if the upper fixation is too hight and that would make the cable too tense? In the last set i got too much circling moves is that normal? Thanks.

some like to put it chest high of ur boxing stance. so itll simulate a boxers head avoiding ur punches.

some likes it really stiff so it wont move around that much but then again it wont simulate a boxers head if it doesnt move that much. i guess u can loosen it up so u can simulate head hunting and so u can avoid the ball when it rebounds towards you or tighten it so u can train to punch quicker.

I know that. What i want to know is about the installation, how am i going to set this height, and the other questions i made in the first post.
