I am looking to purchase these at least 8 of them. But I can't seem to find the right shape. This was the picture my boss sent me so I'm sorry I don't have any other information.

Thanks for posting. I see resemblances between your part and our 32-028 drawer track socket. Take a look at the measurements to see if they are compatible to yours.
