Barbell Bars and Curling Bars with Holder

There are two barbell bars and two curling bars with a bar holder that can hold up to 8 bars.  These were from a high school weight room that got renovated and got new equipment.  There are no weights with these, just the bars and holder.  I admittedly know very little about this type of equipment, so if there is something you need to know you can message me and I will try to find out from someone who knows what they are talking about :) I believe the two larger ones are standard olympic ones.  They are about 86" long.  The curling bars are about 47" long.
