we have four 84" curtains on it and it is holding well
There are 3 brackets for the 72-144" rods. My windows were on the lower end of that range and I did not need the central bracket to support blackout curtains.
Three brackets are included.
It comes with the end cap as pictured. It screws off easily to be replaced if needed.
Hi Blueeyes, yes, it sounds like you just need to tighten the middle bracket tension screw to secure more tightly the rod in place so that it will not move or slip. If this does not solve the issue just reach back with more clear details as to what might still be the problem.
Yes, it does come with the center hook. The rod is it sturdy, but I used them on 100" windows and felt the center support was necessary.
I don’t know as I did not look for it. But mine are holding up three thermal lined curtains, with no issue
It's very sturdy, I put 3 84in long bamboo panels on it.
