I believe you could be referring to a roller adjustment kit that we used to carry but it's no longer available, unfortunately. The only adjustment screw we carry is the 84-502 and the longer screw 84-506. If you need those nylon grommets, see if you could use a type of nylon wall anchor. I recommend checking with a hardware store in your area. |
