RB180 is for extra large round bales with a diameter of up to 180cm = 6' and comes in two different heights:

"Low" which has a height of 175cm, cover an extra large round bale from the top down or a bunch of small bales or a pile of loose hay when used as a large bag with the opening facing up.

"High" which has a height of 260cm, takes a full extra large round bale from the bottom up which by the way is the, by far, the best way of dressing a round bale in a SlowFeeding net.

Same price regardless of mesh size.
