I bought my bar discounted at Amazon. They said it would come in a damaged package which it did but there were also no instructions which was not mentioned. Can't find instructions anywhere that includes using the hex key etc. Wish your vid included that. Now this thing is useless to me. 😕
You have to spin the ends in same direction to expand and spin in the opposite direction to contract. Then when there is contact the middle bar works for the final bit of tightening.
