36 pairs of 20" Drawer Guide Roller Rails, white metal, excellent condition

Description

I did a big kitchen change and had new custom cabinets and drawers made.  The new drawers were a different size then the ones I had made when I built the house.  Because of that, I had to drop some big bucks on new drawer rails.  I have 36 pairs of 20" drawer rails with rollers that I now have for sale.  They are in excellent condition and all work perfectly.  36 pairs are enough to hang 18 drawers.  These are steel, and painted white.  I want to sell them as a bundle.  Looking at other listings, it appears that used they are going for about a pair.  I am selling them all for 0, free shipping.  As a bundle, they are quite heavy.
