we have what seem to be 3 custom height screen doors that each employ 4 of these rollers. All but one are missing. We hope you have some of these. The device shown is 2 3/4" long, 3/4" wide, and 3/8" thick.

Hello! This roller looks like a great match for our 84-034. Look it over and let me know if you agree, or if you had any questions.
