Plastic piece that slides into track

Thanks for reaching out to us. Are you looking for the black slider piece of the hinge? We don't sell that part separately so you'd need a new hinge altogether. Take a look at the specifications of the 36-004-10 and see if they match what you need.

Please let us know if you have any questions.
