Searching for 55 mm shelf clip 3/4" shelf

A quick learner says:
I need some white plastic shelf pins for a kitchen cabinet. The shelf is 3/4", the pin is 5mm in diameter, with the groves and it is a locking one, as you can see in the photos. On the back is printed, "P.X. IND. 34" and below "W. Hanover, MA."
The holes, in the cabinet, cannot take a pin bigger than 5mm and the pin I have is less than 3/16 of an inch, in diameter. Do you sell this shelf pin? An answer would be appreciated. Thank you.

Hello! We sell a few shelf brackets like this. Start by looking at our 32-313 , 32-303 , or 32-299 . I think one of these may be worth considering, though note that all of them have a 1/4" diameter pin. Yours is a little bit smaller. You may want to triple check that measurement.
