Orange Glides and Brackets

These photos are of glide and brackets installed, not uninstalled as suggested. I can see no identifying information on them.

The particular drawer I'm looking at has outside dimensions 16-5/8" x 21". Brackets are 3" tall, 1-3/16" deep and mount on a 1-1/4" hole pattern. There is 17" between the face of the brackets (across the drawer)

I want to add a drawer the pantry section and I would like to replace the glides with a better design, one that works, on all 22 drawers in the kitchen.

I can supply CAD drawings if this helps.
