Real SlowFeeding makes the horse feel better and makes the hay last for longer.
RB Std High A
RB Std High A has a mesh size of 3cm = 1 1/4" that is recommended for soft hay and can be a problem with coarse hay and weeds that might block the openings and stop the horses from getting anything out. It is designed to cover a standard round bale from the bottom up. Just spread the bottom of the net where you want the round bale, lift the sides of the net and place it on top of the bale, pull up and remove the thin baling net, use a shackle or a hook to close the SlowFeeding net, tie the top of the net to a rope coming from the ceiling to keep it on the height where it is. There will be no need to readjust this height.
The actual height of this net is 220 cm and the diameter is 170 cm just to make it easier to dress the bale. I recommend you not to consider this net for a bale larger than standard.
