Sliding Shelves (20882)

I have two pairs of sliding shelves removed from old kitchen cabinets when I repurposed the cabinets.
The shelves are in good shape, but may need some cleaning.

1 pair of shelves 19.25" deep x 20.5" wide (pictured)
1 pair of shelves 19.25" deep x 32.5" wide (not pictured)

(measurements are outer dimensions)

I also have side panel cabinet inserts to hold the rails in the cabinet, if interested. 3 are in good shape, one is a bit damaged.

Thanks,
Matt
