Please see below for estimated weight tolerance for our single and double heavy duty white traverse rods. Single 30-48": 10 lbs, 48-84": 15 lbs, 66-120": 20 lbs, 84-156": 25 lbs, Double, 30-48": 15 lbs, 48-84": 20 lbs, 66-120": 25 lbs, 84-156": 30 lbs, Keep in mind that estimates aren’t set in stone because the less you extend your rod out, the bigger the overlap is for the inner and outer rod. This makes for a sturdier rod allowing for a larger weight capacity.
