13/16" x 5/16" hard plastic piece that apparently works to make 20" soft close drawer sliders stay closed. Sterling is stamped on the side of the slider. Drawers are part of my kitchen cabinets.

Hello,
Unfortunately, we don't have this exact drawer stop but see if you could use something like our screw-on stop 32-125 or even the 10-112 . Take a look and let us know if you have any other questions. Thank you!
